On the ridges

AJ, JIM and T6 launched around midday for a romp on the local ridge. To start with it was working to 800' consistently so we wandered off to Halton. Sadly we had all of 5 minutes on that ridge before clearing for their NOTAM so left at around 1000'. We meandered past Wendover where not a lot was happening, and left the white cross at Princes Risboro' at around 600' for Scotty's house. JIM and T6 arrived at rooftop height and less than 200' but persistence worked out and we scrabbled back above ridge height, picked a therm and cruised back to Booker. A grand day out even if the clenching was pronounced at one or two points.
