I ride the Flatwoods trail only now as well. Back when I was dorming at USF, I used to ride Bruce B. Downs, but since I moved to an apartment just up the rode from the trail I stick to that instead. Still a bit dangerous actually getting to the trail though since it's a busy road. Actually had some kid in his Camaro speed up as I was crossing the road to reach the trail, ended up buzzing me just as I got to the median.
