Metro Cost Calculations for getting to work


Okay, I have been testing the public transportation for one full week now, and I can definitely say that taking the Metrolink to work is just as convenient for me and driving to the garage here. Time for some calculations to see what it will save me to either walk or "Park and Ride" versus simply driving to work. Wash U charges $429 per year for yellow parking, so that is an easy savings right there. Our new house is 4 miles from campus parking so that amounts to 8 miles a day or 40 miles a week. Over the 50 weeks of driving a year that is 2,000 miles at 20 mpg (no highway driving) on my Geo Prizm gives me 100 gallons of gas used. At the current $2/gallon that is $200 in gasoline. The Brentwood Metrolink station is only one mile from our house, so if I use their free Meridian "Park and Ride" garage that amounts to 10 miles a week or 500 miles a year driving or 1/4 the mileage as compared to driving to campus, plus avoiding a lot of wear and tear on my aging car from the stop and go traffic on Clayton/Brentwood/Big Bend/Forest Park Parkway. Driving to the Metrolink as opposed to walking the mile each way costs me 25 gallons a year or $50 per year. I could also ride the bus which would cut the walk in half but takes 20 minutes instead of 10 minutes to get to work.

So now I will break down the options:

1) Driving to work and parking on-campus: $429 for parking plus $200 in gas plus increased wear and tear on the car. Plus I am adding the most to the problem of traffic congestion, natural resource usage and air pollution. Total travel time to work 10 minutes (unless their is an accident slowing traffic).

2) Drive to "Park and Ride" and taking Metrolink: $50 in gas plus some minimal wear and tear on the car and I cut my traffic impact and emissions by 75%. Total travel time to work ~15 minutes.

3) Walk to Bus line or Metrolink. The car gets to just sit in the garage or could perhaps be sold! The walk to the bus stop is 8 minutes but the ride is 20 minutes. The walk to Metrolink is 16 minutes but the ride is 10 minutes so they are a wash in terms of time. I would get more exercise walking to the Metrolink but the walk is not as convenient through the commercial and industrial areas on the east of Brentwood Boulevard. I may have to invest in some deodorant for work, but I am sure my co-workers would appreciate it!

Trying out the L'Ecole Culinaire Presentation Room restaurant

Image
We had been seeing the ads for the restaurant at L'Ecole Culinaire and since we live so close by we thought we would try it out. We had always enjoyed dining out at cooking or hotel schools like the CHIC in Chicago and the Statler at Cornell where we went to college. Since we still love to go out and eat here in St. Louis , we ventured over to their restaurant on the first day they were open for lunch. The first thing we noticed is that they do not have much parking! They really need to let patrons know where they are supposed to park. The restaurant itself is small but very well attended. There was one fellow who kept straightening all the centerpieces and place settings on the tables, and we always saw one or two student workers milling about. The lunch menu was small and the choices did not appear overly "gourmet". The special of the day was a bison burger stuffed with cheese, and other choices picked by my group included a club sandwich, a "margherita" pi...

BMI & BMR Calculator (Body Mass Index and Basal Metabolic Rate)

Image
My wife has been researching type 2 diabetes and recently checked a book out of the library which included a body mass index (BMI) chart much like the one pictured here. Whereas it is fairly easy to follow, I, of course, think it must be converted to an online calculator! However, when I checked the Internet, there were already a billion of them so I had to make one that was different. So my lovely BMI BMR calculator accepts either inches or centimeters for your height and pounds or kilograms for your weight and calculates not only your BMI, but also your BMR (basal metabolic rate) which determines how many calories you should consume! So I made a spiffy "all in one" healthy body indicator calculator which not only determines how underweight or overweight you are, but also tells you how many calories you should consume to maintain or improve your ideal weight.

Not all Frosted Window Films are the same!

Image
We live in an older home with a lot of issues and one of them concerns our back door to our patio from our sunroom. The door has double paned glass on it, but unfortunately the seal has broken so you can see moisture collect inside of it. We decided the easiest way to "remedy" the problem was to cover the window with some "frosted" film so we did not have to see the moisture condensing between the panes. But the question was, what film? There are a bunch of them available so we had to select something to try on the door. The first place we tried was our nearby Lowe's store which had a bunch of Gila brand film. We selected what seemed like the typical adhesive based door sized  film that cost about $25 after tax. We thought it could not be that hard to put up and look nice on our door. So one day my wife ran out and purchased it at Lowe's and we commenced to install it on our door window. We made our own soapy water solution and followed the directions...
