My parents used to take their 2 week vacation primitive camping on Kerr Reservoir near Danville, VA. We had a huge canvas tent for the 7 of us, plus our Saint Bernard. Mom cooked on a Coleman stove. We kids were about 2,5,6,8,& 10. I can remember Mom washing out diapers in the water (I know, right? Yuck!) and hanging them up on a clothes line. There was no running water or electricity, just an outhouse up the road. We kids spent all day, every day in the water until we were sunburned and prune-y.
I don't know how they did it. There is NO WAY I would spend 2 weeks primitive camping with 5 little kids (one in diapers!), no A/C, no showers, sleeping on the ground, no kitchen and no easy bathroom access.
