We camped @ McKinney this weekend. It was so much fun. The lake water is a great temp for swimming. We went for a walk and scouted our loop for the rally. It's perfect! There is a nice flat paved loop for the kids to ride bikes and stay out of traffice from any moving cars. I guess for the potluck it's BYOC (bring your own chair) and we can set-up in the loop. Looking forward to it.
