TheDoog. Interesting comments and they somehwat mirror my take on things. In the twenty years or so we have been caravanning there has been a marked change in the attitude of caravanners to other caravanners. In the early days, I would go for a barrel of water to return to the question "where have you been all this time". Well, talking of course. Had more converssation over the stand pipe than I have over the bar. As you say, people would stop and chat, even if its a quick good morning. I found now that many of them even avoid eye contact and Im not the only one to have noticed.
I know I shouldnt generalise, but I found motorhomers very much aloof, whilst tent campers are glad of any contact. Caravanners are hit and miss, either they wont talk or they wont shut up. Its the old Monty Pythons syndrome, I look up to him but I look down on him.
I cant put my finger on why this seems to be happening, but i do yearn for the old days and a 90 minute barrel fill.
