Foot Power. I rode my bike for the first time since September. It needs a tune-up since it's been outside through the winter, and I had to put some air in the tires, but other than it felt great. I have a new level of mobility now that the weather has warmed up and the streets and sidewalks are (mostly) free of ice and snow. I'm no longer beholden to pals with cars and/or the spotty service of local public transportation. My legs burn with the sensation of freedom... or is that just my pedalling muscles aching because they've been dormant for so long? Whatever.
