Detroit. It's... a mixed bag. On the one hand, fucking everyone tries to run you over if you use the road in the suburbs. Even people with bikes strapped to the bed of their lifted diesel pickup trucks. Then you get into the city. If you're in downtown or midtown or any other gentrified area, everyone is from the suburbs and will treat you the same way, but there's also bike lanes so you're not entirely fucked. Just can't ride at night because you need to spot the broken glass as you're riding, dismount, and walk over it. It's also a good idea to wear a scarf over your mouth so you can breathe if a diesel truck passes by. There's also a new indoor velodrome in midtown and in spite of the false reputation, the poor neighborhoods are really safe to ride around in. Most murders are either people who know each other and bar fights, so I don't ever really feel unsafe. No one's going to rob a guy on a bike when there's all these pedestrians walking around anyway. There's a few trails in the suburbs but they're constantly clogged by old guys on $10,000 bikes with spacers stacked a foot high who think it's ok to take up both lanes of a thin trail with their 10mph 5-man peloton... There's really no excuse for riding a Madone 9.9 at 10mph on flats with a tailwind while drafting several people, but I've seen it happen.
