Besides the exercise, the cheap fuel, the green of the trees. the murmur of the creek, and the free parking spot right at the Redistricting Board's door, biking gives me avian symphonies every day, and once in a while I get to mingle with a moose in its natural habitat.
My ride from the University area to downtown is about 3.5 miles and maybe half of it is on the Chester Creek bike trail. It is, without a doubt, the best part. And a moose picture let's me put up a really short post.
