The worst experience -so far.
Wanting desperately to fly. Push the glider some 2 miles down the taxiway, the momnet we arrived at the beginning of the runway the wind changes direction and flight is simply cancelled because local regulations prohibit taking off on a southern direction for reasons of noise! Yes it was a Piper Cab towing.
The best thing is the unbelivably low noise levels - no engine eh!
Additionally it is pure flying!
