I might go down there for some riding later this year. I am 12 hours exactly, North on 95 in VA. Maybe I'll take a long holiday, find a GF, make her come with me, and hit hardrock for a long weekend. I like the "GP" track too. Not a big fan of the other little 2 tracks. (the sand and the outback)
I used to hit the water tower to double, (i think it's faster) but my friend Jaco (south african guy) used to hit it wicked on a 450 to triple, he'd catch that small hump down the backside. just ridiculous. You can hear that 450 from across the property 30 acres away... BWAAAAAAAAAAAAAAAAAAAAAAAA (someones hitting the water tower)
For those of you who has never been to hardrock FL, the jumps are massive, and the dirt is like cement, it blue grooves, so if you fall, it's a collarbone usually at a minimum.
