I love the title of this thread. I'm in the same boat. I only took one lesson, because I'm cheap, but then watched the Progression Beginner DVD (which I found very helpful), and I'm up and riding around. I'm hooked, but I can't for the life of me figure out how to stay upwind. The learning curve in this sport is very steep. I've taken several 1 or 2 km walks of shame.
I've had about 3 or 4 successful go's at it, but I've had about 10 trips to the lake, where I just launch the kite, go out, and find there's not enough to get me up. I live on the Central Coast, so there's 2 or 3 good inland lake locations, but the wind is gusty and unreliable there so far. I finally got the guts to go the the ocean beach last weekend, and it BEAT THE HELL out of me. I had a few inadvertent body dragging lessons that day, and was sore for a week.
I'm sticking with it. For the brief periods of time that I do get up, only to drift a half a Km downwind, I really love it. I can't wait until the day when I can launch and land at the same beach without a walk!
Oh PS... If I did not persevere, the wife would KILL me, as I spent $2,500 on a kite and gear.
