Welcome to the board! There are plenty of Tampa members. There are a couple coming out my way tomorrow. You're more than welcome to come if you can make it.
You should take a look, once you have access to it, at the threads about pit bulls and SchH work. I don't have any experience personally, but from what I've read, pit bulls aren't the best candidates for that kind of activity. Weight-pull, on the other hand, is right up their alley. SchH is possible with a pit bull, but your dog has to have the "just-right" drive, temperment, etc. Pit bulls are also really good at agility!
In any case, this web site will more than likely have answers to any questions you may have. If not, just post a question in the right section and we'll all be happy to try to help you!
