There is a conflict of doubles tourneys on the 20th. There is the City of Mobile doubles on that day as well at Cottage Hill and Muni. I believe it is a cross town traffic event, and I am not sure if it is a SN qualifier as well. But since you usually get a big turn out from Mobile, you should know about this conflict of close tourneys.
Keep up the great work in P-cola, I love to see disc golf grow and grow.
