Problem with new trailer, or is it the grandson?

My daughter isn't speaking to me now because I didn't invite them to go camping with us last week. Her eight year old son is into everything as well. I don't like these quiet spells but it sure is peaceful and relaxing. When she gets a handle on her son, they'll be welcome to go camping with us. How she does that is up to her and his father. One of the most common campground complaints is undisciplined kids running around with no respect for other peoples' space or property.
