The problem with holding something like that in Blackpool is the risk of damaging the sport in the public eye.
Blackpool is a boozing town - it's based around getting bladdered, getting felt up by some scouse slapper, then getting fleeced in one way or another. (usually robbed by said slapper)
It only takes one bloke to buy a paintball marker (even the toy ones) get bladdered then shoot his mate in the eye before the press will pounce on such a "dangerous" sport.
We all know that's bollocks, and that it is safe as long as each and every participant values their eyesight and follows the rules of goggs on, all the time, no matter what when your barrel sock is off.
But, the press don't ask for details, they just presume that 5 minutes of google time is enough to understand the sport.
