It is difficult. Our group at one time consisted of DW's boss, who was a few years older, a co-worker and one of her husbands co-workers. Plus another couple a bit younger. Our girls were really the only kids. That group lasted several years then we drifted apart for a lot of reasons. To be honest, we camped a lot, almost every weekend. Our girls usually found things to do and could always find other kids. Start camping in state parks and NF camp grounds, places where families can aford to go, not resort type places.
