Never rode their but I think i know where your talking about.
Is it the dead end of Westshore by the old Port Tampa junk yard ?
If you live around their LOCK YOUR BIKE UP REALLY REALLY GOOD.
As far as a petition I don't think you'll have much luck.
I live in Town & Country, there's no place to ride around here either.
There's a little place to ride over by M.O.S.I. (Pepsi Cola)
They fenced off the place at MOSI. It is gone, my buddy has been riding there for 20years with never a problem. I have parked my truck & trailer in the state trooper parking lot when a patrol pulled up & did paperwork, he just waved & nodded & we kept riding, but it is GONE NOW!!!!! People stated dumping junk out there, last time we were out there we found an old cut up atm machine.
