I went to the Nashville edition of Red Bull Flugtag. I had a blast (except that friggin' sunburn and dehydration). We actually saw the North American distance record shattered. It was formerly 80 feet or somewhere close. The guys who broke it went 155 feet off a 30 foot ramp. A 5:1 glide ratio isn't bad for a homebuilt hang-glider. If the Flugtag visits your city, I'd advise you to go check it out.
