In my own backyard

My training has led me to rediscover some simple pleasures, like getting out in nature, and a trail near my house. Here in Tampa, in the heart of suburbia, there aren't that many nice places to take a walk. Never mind that this one runs next to the county landfill..it gives the illusion of hills...which brings up the next subject - that there isn't anywhere to train for the kind of trekking I'll be doing...does going up and down the overpass on the highway 10 times count?
