20th might be difficult for Mr.RL and I've just remembered that it's my sister's 30th Birthday that day!
Hows about the first weekend in August, ie 2nd and 3rd? Would this date also suit Barney and SteveM?
There is a DarkPlaces bash in the Lake District that week, but I've checked that list and I don't think this would affect anyone?
At risk of upsetting someone (something that seems very easy!), shall we aim to make a weekend of this and find something to see on the other day of the weekend?
Hello again darkness, my old friend...
