I think there are more than enough kids in southern Chester county to build and sustain a club lax organization if they start with just the younger ages and build from there. You won't be able to form high school aged teams overnight, but no reason you couldn't have 2027-2029 squads and just annually add new ones at bottom age group as long as you get some solid coaches willing to teach. You don't need to be a national power to sustain a club, just find your niche. Look at Fusion. They tend to struggle on the field and go to less prominent tourneys, but they get lots of kids coming out each year as they have great coaching and kids who can't get playing time on clubs like Freedom, Mesa, Roughriders, Brotherly Love, etc. who still want to play club lax. No reason a SoChesCo Club couldn't exist.
I agree a club could exist in Southern Chesco, but no need to call out struggles of any local clubs as an example. We should all work together to promote lax in this area. Fusion has a great box program called PennLax which is there focus and they do a great job teaching indoors and out.
