In making my plan to commute to work I found that there are 9.0 miles of bike lanes in my trip, with the only stretch without being the one from my driveway to the pavement. Some areas the bike path is very narrow, but it's still there. In the morning ther are commuters in cars traveling at high speed, in a rush trying to get to work. and they aren't very polite to other motorists. There are a lot of roadside memorials, too. I'll need to be careful because I am thinking they won't be expecting a bicycle.
Frankly, this is Arizona, the state with the stupid driver law; it might be smarter to try to stay out of the way. "Bicyclist Wilbert Ulmer, 85, of Mesa died Tuesday (Jan. 10, 2006) when a pickup truck struck him as he crossed the street in the 9200 block of East Southern Avenue in Mesa. He was not in a crosswalk." East Valley Tribune Article. That's an 85 year old cyclist. Shame really, there aren't too many of those.
If you don't think this is serious -- try this google search and see just how many news stories there are about cyclists being run down by cars or killed. I89 since Boxing Day. That's a lot.
Bikes belong on the road here in Mesa, so you don't have to be a Dick. We should be trying to enjoy it, because there are a lot more hostile places than this.
