Well, I wrote a while back that my lack of health insurance was keeping me off my bike. I'm happy to report that this is no longer the case (although I'm still working on the insurance). I think I was just in a whiny mood :)
Despite my suburban location I am lucky enough to be a mere 2.1 km (1.3 miles) away from my favorite supermarket. That takes me about 22 minutes to walk, but it's much faster on a bike, and I have a good route. There is a minor, residential street directly parallel and adjacent to an arterial street. It's kind of like having a physically separated bike lane. It looks something like this:

There's no formal bike parking at the spot, but the people who bike there improvise by using street signs. I don't have a basket on my bike or anything, but I have gotten good at balancing two grocery bags, one on each handlebar. I've considered taking transit, but the service is so infrequent out here that it's usually faster to walk.
So, the bike wins. Free exercise, no gasoline required, and good fun.
