I was in the hang gliding business in the early days of Windsurfing.Diane Sweitzer sent letters out to all the listed hang gliding businesses offering dealerships.I was already familiar with WS because a client, Steve Skilkin, showed up with his WS and spent several hours with me on Lake Michigan, trying to get me started. I did become a dealer after a bumpy start, Diane was irked that I'd printed a pamphlet without clearing with her.I built a better version of the mast base & telescoping mast.
