Been away for a couple of days, so first chance to look at thread. Thank you all very much for your opinions and advice, some really interesting replies, which have given me food for thought.
I think I'll book a trial lesson initially, (although I understand now why they are elevated in price, but it will give me a good chance to assess the club before continuing). Also, as suggested by some, I will also endeavour to try both traditional and motor gliding.
Can I ask one more question? The human body requires supplemental oxygen around 10,000 feet - how can you soar to 20,000 feet plus, and remain conscious? (assuming no OX2 or pressurisation).
Thanks once again
