I'll try and give some semblance of an answer to Letme and soccer63 from what I know:
Bridge won't be an affiliate of MPSC because MPSC already has its own Select/Classic/Challenge/Premier program. The Powers That Be at MPSC/Mt. Pleasant Town Hall aren't going to give it up so they can wear red and gold and be Bridge FA instead of maroon and white and MPSC when the program is part of the Rec Dept.
For Bridge, the problem is that fields are expensive and hard to find. Most of the current land in Mt. Pleasant either belongs to the Rec Dept, public schools, or is already "leased" out to be played on by MPSC. And that's something that's shared with other sports. Daniel Island land is either BE, Charleston Battery, or private AND they have their own (correct me if I'm wrong) Daniel Island Soccer Club for boys.
If they move away from their target area of Mt. P/DI, you run into James Island...which is used by James Island Soccer Club, West Ashley and North Charleston used by CUSC, and Summerville used by SSC.
That occupied soccer space means that Bridge would have to buy or lease its own land, turf the fields, maintain the fields, provide restroom facilities, and parking. I don't know about prices elsewhere, but if they want to stay in the Mt. P/DI general area...even just buying or leasing the land gets really ridiculous.
And, without a rec/supporting populace of players to bring in money, from what I know, which admittedly isn't much, Bridge is way too small a group to be able to afford paying for land, building a complex, and keeping it up on its own.
