PS For what its worth I believe that Genghis has a point and that some gliding sites are very unwelcoming. What both the powered and the gliding fraternity need to remember is that we both have our fair share of "idiots" or "the misguided" - unfortunately, all forms of flying are unforgiving of neglect and carelessness.
PPS Hinton manages to keep free-fall para, gliding and powered flying apart from each other, Halton with powered and gliding and also Gamston with powered and gliding - as long as you all have a good understanding of each others needs and procedures then all can work quite nicely.
Good luck
