Hi Uli,
Ya I guess I shoulda explained. There are tows from a guy named John Templeton, starting end of this month. The time I wanted to go there the powered glider people are having a camp, and taking up all the ramp and tows. So, as long as you don't wanna go the 3rd week in June, there'll be tows from a 182.
Call Parowan Air services and they'll get you in touch.
