Emp,
I ride trails, road, paths, grass, etc.
Mainly, trails and roads... What is your price limit? There are a lot of good deals on Craigslist, but many people are asking $200 for an $80 bike! Are you familiar with decent trail bikes? PM, should you wish to discuss further...
FYI, I always pay attention when I ride! I've almost hit - deer, bunnies (not our Bunni!), fowl, snakes, etc.
