If you are going about setting up the club Kev, you may do some ground work within the halls of Frank Towers and get co board backing, because you are sure as hell going to get a fight from the club in question. In time, you’ll have to work with them, but they will inevitably do what they can to stop any new club forming. So at least if you have a good action plan, a breakdown of a 5 year development proposal for the club (plenty of good examples on line of established clubs) and the support of the board, then it will make it easier. you may not like the board or want to deal with them, but they will be the only ones that matter. In time, there may need to be an agreement between the clubs as to schools in the area and who has access to them. Getting into a school is a huge thing.
as mentioned above, starting with underage may be the easiest. Setting up a nursery basis and up to 10s might encourage newer parents to the area or ones without a GAA background in. And then its a trickle effect from there. once its in a couple of years, any older discarded players may start showing interest and it should take off from there.
@Pikeman doesnt be around here much if at all anymore, but I am nearly sure he was involved in starting up a new club in Dublin. If not involved in its establishment, he was heavily involved in the running of it early doors.
