Depends. I would guess 6-12 go-fasts...maybe more. Rest of boats will be smaller run-abouts and some cruisers. At the very least, the PC will be fun. I think the one at Texoma on the 1st will be much bigger. EM one is only a $50 per hand buy-in.
I think there is a spot behind me on my dock (36 ft slip). I will check tonight when I go out for an evening cruise. I wont be there until 10am or so o nSaturday, so no rush.
