Nice story summing up one the many reasons we RV. We started RV'ing back in 1990 with a group of Ham radio operators called Klara Kampers, about a 120 of us all together. Anywhere from 10 to 20 members would go out camping somewhere local each month. Great time always had by all members with the plus of meeting new people each trip.
I find that campers where more open and friendlier back then, than they are today. We still find a few camper each trip but they seem to be fewer and further apart than when we RV back in the 90s. Maybe it has something to do with RVs having more goodies inside. People don't seem to sit outside as much especially in the evening. I remember getting up each morning and going outside, fire up the Coleman store to perk a pot of coffee. Actually two pots of coffee as people would come over with their empty coffee cups. Today on our trips the only thing that happen while making the morning coffee were people asking me why are you making coffee outside and using a perk-a-lator? Seem nobody comes outside much anymore to just walk around except to walk their dog.
Maybe we need to limit the time campers are to watch TV and use their cell phones? Then people would come out of their rigs and talk with other campers. I miss the camp fires with 20 to 30 people sitting around and talking through the evening.
Just in case you haven't guessed I am the guy that walks up to you and starts talking. So beware I am out there walking around and will stop to talk to everyone I find outside.
