This is something that was common back when I first went there. The mid-winter school vacations in Vermont happened at the same times. Mostly the last week in February into the first week of March. It was that way because town meetings were on the first Tuesday in March. So it made the break a week and a half. That is how a lot of us could afford to drive down and still have three or four days in the parks before heading back home.
Anyway, The first and second time that we went as a family, even I could not believe the number of people that I met that I knew. None of us had known that we would be there at the same times. At least two to three times a day I would hear my name called from behind me or to the side and sure enough there was someone that I knew. By the end of those two years, my kids were convinced that I knew everyone in the world. I was starting to think that it was pretty freaky myself. After that it hasn't happen at all. I cannot explain it, but, a happy coincidence I guess. I know driving down on I-95 it was fun because if we passed someone or they passed us and we had Vermont car plates, we'd blow the horn and wave at everyone in the other cars.
Also back in that time I would met people that I didn't know, but, we'd strike up a small talk discussion and find out that we lived very close to each other. One time I met someone and was chatting with them, I think it was at the hotel we stayed in and found out that they lived less then a mile from us and another time, while having lunch at McDonalds in St. Petersburg, Fl. we over heard people talking about heading home to the town that was just to the north of us. Small World indeed!
