Find a bike community... or make one! Especially if your city isn't necessarily bike-friendly this is a great way to stay safe and have fun.
Also, be sure to know the basic bike laws in your area. Some states require drivers to give more gerth between vehicles and bikes than others. In general I've found inner cities to be better biking destinations than suburbs because many people in the burbs aren't familiar with the fact that bicyclist do have rights on the road if a bike lane isn't available. It's not necessarily their fault, but a consequence of urban planning that doesn't take work biking commutes into consideration.
