Scott, because you are a class individual and were so nice and complimentary of my DD at the Adidas tryouts a few months back I did the research on PGF's site.
I came up with the following:
Cancelled
Indiana would have been held May 25-27
Texas this past weekend
Colorado June 15-17
Minnesota June 15-17
Southeast June 15-17
Northeast July 6-8
North Texas July 6-8
That means that the only ones that were/will be held for 12U are SoCal, Arizona, Nor Cal and Northwest.
