Also live in fife. The fort is my regular site. They also have a new indoor site that is slowly opening up just now. Played in it once and it's pretty good. It's huge though and only about 1/4 is finished. I've been to crail a couple of times and it was always good fun but it's a little small. Never been to section 8 or the other indoor place in Kirkauldy but I've heard they're both good. With section being of similar size to the fort.
The fort really is good though. The folk there are awesome. The marshals all listen, the players don't cheat and the games are fun. It is outside though so it does get cold sometimes. And wet, and muddy. But hey, Scotland. I can't wait until the indoor site, code name; The Fortress, to open up completely.
