A couple buddies and I went to Fire Wire Ziplines in Blue Ridge the other day. It is supposed to be the most extreme zip line in the country and I believe it. This thing comes off a mountain like 30 stories up and it is a like a free fall for the first half of the ride. It is a total adrenaline rush. It only cost $30 for the first ride and $15 for any other ride so its pretty cheap for a huge rush!!!
If you don't go see these guys and ride there line you are crazy.
