Ahhhhh, why not a full season team? Take a look around your area and see what's there.
yeah, not sure why you didn't go full season route to begin with, but I suppose you have your reasons. You'll need to look to latch onto a team for the second half. There are usually a good number of kids that unexpectedly make their high school team and leave an opening. But it probably won't be a strong program, where kids are committed to the team for the full year.
