Jo has suggested heading for the Wye Knot Inn in Symonds Yat to meet up and head to the caves.

Who is planning on going and should everyone meet up in Cheltenham to rationalise cars first?
Mungo is going at around 3 and will have 2 car spaces for people who want to help set up, I'm happy to wait until the later group if there's a spare car space. Please confirm here if you're willing to help setting up and I'll put you in touch with Mungo and Jo. There's space for 3/4 cars near the path to the caves.
