USAMP was one of the driving forces behind starting the CsPL. There has been much opinionating over whether or not the secrecy surrounding it's formation was meant to keep the SSC/CBSC teams from having games.

Whatever the real reason for the league's exclusivity, October 13 is the weekend of USAMPs Charleston Select shootout so I can see why SCYSA Coastal would assume none of its member teams would be busy that weekend since any team playing in it is directly funding a club that is a root of the headaches.

If you need other tournament options, I'd recommend considering the JIYSC tourny in mid-late November and/or the CBSC tournament later in October.
