1976 - Hobbie Hawk R/C sailplane on high start lauch. I loved this glider. I did a lot of thermalling with it. It was a joy to fly and tricky to land with no spoilers.

1982 - Moyes Mega II, just before I sold it. This was my last hang glider. I had converted it to double surface at one point and it flew much better than stock. I had many wonderful flights along the Lake Michigan sand dunes from 1980 through 1982.
