Our first week camping, we were fortunate to have as neighbors two very nice 12-year-old boys who would place "chase" with Munchkin for hours. The second week we moved to the other side of the park and had neighbors who sat by the campfire every evening and played professional level bluegrass. It was lovely and Munchkin got spoiled by getting to fall asleep to the music every night.
There weren't a lot of kids around, however, so one afternoon when we ate lunch outside the lodge, Munchkin was delighted to find a 5-year-old boy and his 2-year-old brother. The boys played and played. After spending a little time only with the 5-year-old, Munchkin said, "Let's find out what the noisy one is doing!"
