Hi Jinx (?)
Thanks for the comments.
This shoot at Quarry is part of the UKAHFT series of competitions, attracting shooters from all over the UK. it is an open comp, I don't believe you have to be a member of a club. You could cherry-pick which of the events to take part in & was most convenient for you to travel to. For instance & bearing in mind most of the comps are shot on a Sunday you might want to find another venue to shoot on the Saturday. however there's a couple where it is a two-day meeting, Saturday and Sunday.
