Just returned from taking my oldest grandson (4) camping for the weekend. The private campground had planned activities. Took him to the open meet of the White Creek Railroad which is 1:8 scale trains. This is the 3rd largest layout in the US with 5 miles of main line and just short of 8 miles total including side tracks. The members give guests a ride, typically about 20 minutes. Our host had us out for more than an hour. Great fun!
The kids got to make their owned shaved ice, created fathers day cards, rode the "train" ride in the campground (little cars pulled by a golf cart) as well as hay rides and all the playground toys and pool. Little guy ran his little legs off and slept like a log.
A great weekend for both the grand parents and the grandson.
