Trying to be Green

Earth Day was April 22nd. We had a growler special in honor of the day and I know most businesses did something to celebrate the day.
I was on a plane. My celebration of the "green day" consisted of flying back to Denver, getting on a shuttle to my car and ordering take-out. In many ways--fail--driving and take-out with containers.
I failed, but there was some success. Instead of taking a taxi to the airport, I boarded a bus, with 45 other people. I walked to the bus stop; again, another green option.
In many ways, I have been trying to become more green in my life. I carry a to-go coffee cup instead of purchasing a throw away cup.
I walk, most, everywhere in Denver. Not only am I saving money on gas, but I am enjoying the sunshine and the lack of stress that occurs when I drive. I get extremely frustrated with other drivers. I know--shocker!
I hope to have my bike serviced so that I can begin biking to work. The bus is not an option since it quits servicing the area after 5 pm. Biking would enable me another option to get to and from work. Walking at 2 in the morning does not appear to be too promising or optional, at this point.
I read the weekly, Change the World Challenge on Wednesday, posted by Reduce Footprints. I enjoy their blog and follow the challenges. I participate when I am able to and interested in the challenge.
In honor of Earth Day, I am participating this week. I am modifying it, though, a little, so that I am able to make it work.
Here it goes--
For this week, reduce your showers by 50%. Shower every other day.

For me, this is not an option. Not because I am unwilling, but due to work and ability to sleep. I shower, often, after work. I need to. I am coated with beer, wing sauce and liquor. Did I mention the beer? Dogs love my shoes. My co-worker, Tiffany, had a dog, Anna, who would guard my work shoes if I went over to Tiffany's house after work. Anna protected them from the other dogs and groomed my shoes, at will.
Seriously, as it gets warmer, a shower is a must, after work.
Here is what I propose to do. I will cut the amount of time I spend in the shower by half and wash my hair, every other day. I hope to shower in 5 minutes or less on days that I am not washing my hair.
For one week, I believe I can do this. Can you?
While in New York, my showers were swift since there was little pressure and the shower was consistently lukewarm. Showers are a luxury and I intend to speed mine up and minimize the excess.
Good luck!
