I also vote for a Saturday GTG. But that's just because I have to work Friday night.

If "camping" is desired, something is going to have to be done quickly. COE lakes (Oologah, Skiatook, etc.) are nearly booked full for the Memorial Day weekend and many spots are taken before then. For the "waterfront" sites, people are coming in 2 weeks early so they'll have it for the holiday.

Day use fees apply at all COE lakes. Shelters are $50 if we'd like to have some shade &/or be prepared for rain. For more info on Corps lakes, poke around at: http://www.swt.usace.army.mil
