I used to teach people gliding too, I miss my flying days. Two of my best paraglider flights were a 60km thermal cross country flight, landing at my mates farm for a cuppa tea and a lift back into town. Stupid really, I should have gone much further and set a country record, it would have been easy to do that day.
The second one was ridge soaring past sunset, and carrying on flying whilst the full moon rose. So beautiful seeing the silver bottoms of leaves on trees, hearing owls hooting, cows lowing, and jackals calling in the fields below. That was one of the most serene and unreal flying experiences I've ever had.
