Welcome to the group.
The IOM is beautiful, but I always have a little bit of sympathy for airsofting islanders because the wind nearly always blows near the coast (not good for airsoft accuracy), there is usually only one or two sites (if that) and travelling to bigger games on the mainland is a PITA logistically and financially.
I know on the Isle of Wight they have a really good site community and they are never complacent, always adding stuff to their site. Dont know much about the IOM scene ?
