Hello from sunny Orange County, California. I finally decided to start commuting to work 2 days a week via bicycle (35 miles one way). Yes, gas prices have forced me to finally look at this as an alternative. Even with a car that gets 30mpg, spending $6 a day on gas to and from work is too much. I'll only drive once a week, and be carpooling (with my wife) the other days.
I managed to get my old Schwinn High Plains (15 years old) tuned up and running again. I'll ride the beast for a few weeks until I decide (ie., save up enough money) on what I want for my next bike.
For those of you commuting on the Santa Ana River Trail, be on the lookout for a 6' 3" 220lb guy riding a mountian bike. Anybody that lets me draft will get a big thumbs up!
