The last time I used 7000' of runway...oh, wait, I never used more than about 3000'. And that was in a Bonanza, but at 650' field elevation. Naw, I can't back that up. But I will say that one of the funniest things I ever witnessed was letting an old friend from Michigan bring my old Beech Sundowner into Loveland. He kept trying to get down to pattern altitude...of around 1600'. I had to explain that wouldn't work at KFNL. It really freaked him out.
