One very kind glider pilot here has offered to take me gliding. My fear is I will take to it and knowing me would want to fly high.
Do take him up on the offer. You'll remember the experience. Can I suggest you have a winch launch rather than an aerotow - more fun and significantly different to other takeoffs.
Why would you want to fly high when all the interesting stuff happens low down. (Yes, I know I'm exaggerating)
