i'm in agreement with most of what has been said. the roads are pretty bad, but there is almost always a decent way to go. i swapped out my 700x28s for some 700x32s and that made a big difference.
i'm thinking about buying a three speed cafe style bike. Felt makes a pretty tasty one. i like my single speed IRO, but you really need to pay attention to all the cracks and holes in the pavement when you're riding on those skinny tires... there are even a couple spots with old abandoned street car tracks still in the street. i lost that particular battle. a wider tired cruiser/cafe type bike will let you enjoy the sights a little more.
bullet proof tires. a must!
