Marble rules are posted: here's the link: http://www.landofmarbles.com/marbles-play.html
There are suppose to be porta poties and tables by the weekend.
I have badminton supplies, will set up a marbles playing area, and have board games. I'm sure I can find other lawn games too, but would appreciate it if others bring their own.
I have a barbecue grill and will be bringing it. It looks like the weather is going to cooperate!
