I guess most members had seen the weather forecast and decided to stay at home so we were somewhat short-handed, so, we pitched in to help Colin position the new generator home over the hole in the ground. On discovering the booked TLs were on their way we decided to make the effort and get winch and a glider out. First launch managed 30 minutes off 2 thermals (2,300′ being the highest). After that, more modest times. John T climbed 300′ on the edge of a shower while the glider was getting a good washing. Reports of lightening being seen as Graham T and I landed resulted in a tea break being called. An odd cloud formation appeared above the field which Graham T (impressively) as mammatus. Richard went off to explore taking the last flight of the day.
