Thanks for the tips.
No problem with having enough kids to play with, we have 5 boys all under 9 yrs. They have a great time when not trying to kill each other.
We had a nice campfire in the back yard the other day until they got tired of toasting marshmallows and started playing with pointy, flaming sticks
I think we'll have to do a dry run at home first before we pack up and drive over to the nearest state park.
