Despite living in San Diego, my tires have had a slightly silver hue most of 2010 from the aluminum from my rollers w/ headwind fan.

~It gets dark almost immediately after I get off work this time of year.
~It's also rained many weekends this year.
~I'm encouraged by the precise data on my workouts & progress because the resistance is a constant.
~I've got plenty of TdF vids, and the fan makes just enough noise that I don't have to listen to Paul&Phil's repetitive babbling about "got the bit between his teeth" or "up on the rivet"
