I laugh at these discussions of $40 a night. Those days are long gone here in NJ, especially in the peak season near the shore areas. The CGs are bringing in $60-$80/night, and that is usually only for 2 adults, so kids and visitors cost extra. Then again, most of these CGs have all kinds of programs for kids, which I don't use.
I just booked Jellystone in Delaware for $65/night for a full hookup pull through site. There are a lot of things for kids to do there, but we don't have any kids to take advantage of it. I'm going to start looking into state CGs that provide at least electric. DW will not go without her A/C! ;)
