For the last few weeks, I've been obsessed with the idea of biking with Singer. After checking out Craigslist for bikes and coming up empty handed, I bit the bullet and hit the big box stores. I ended up at Sports Authority, choosing between a "comfort bike" (shocks on the nearly 6 inch wide seat!) and a mountain bike. Feeling optimistic about my ability to master two wheels, I went with the mountain bike. The salesman was quite concerned when he realized why I wanted the bike, especially after he saw me trying to test out the bikes in the aisles. In any event, four weeks later, Singer and I are competently cruising around the block. The trick is to keep the leash short and to let go when necessary. Otherwise, it can get ugly.
