I'm hoping to make it, but may be doing the Dawn to Dusk the week before. Though that shouldn't stop me, unless funds get too horribly low. I've promised someone a lift in an R22 from Wolverhampton; can't remember who, details are at home and I'm in LA. If I manage to get the UK conversion done, and can get two more passengers, I may take the R44 instead.
Sorry to be as imprecise as usual, but I really can't be more certain than that.
