Not surprised at all. We get quite a few guys asking about buying kit from us (which we don't), and they suggest they could play in their local woods, fields etc. (Which could result in an arrest). In the same breath you hear these guys talking about it funny doing driveby's etc... muppets.
Not sure on the legality of the above site though? Certainly not good advertising kids parties, and admitting no insurance though (What else are they lax on). Total cowboys.
