Warp, I laughed out loud at this. Sounds just like something my father could have said. Only he would have added, " All you ever hear about from those old farts is all their aches and pains and what pills they're taking!"
Guys, since we are drifting, what ever happened to Z. Harv, you know? Glad to see Sno back on.
Back on track, duckbutter, lots of these decisions seem hard (and to an extent they are) but the fact you are thinking about alternatives suggests to me you will be happy wherever. I also echo the point that your point that kids will be a natural intro to others.
As adults, we went from Brooklyn (still the longest place I have lived for 9 years, loved it, at coming upon 41), to far out Suffolk NYC sub/exurb to near-in Nassau suburb. We're happy, and we have an almost 10 and a 7 year old. We moved from Suffolk (ironically) because my commute was too long. Ironic because I have been remote work since March. (I know Long Island is not on the map for you, and not suggesting it; just highlighting the number of moves we've made to say it will be fine and great wherever you go).
I think a lot of adults find it hard to make new adult friends before their kids are 3-5; Kindegarden (sp?) makes it very natural. You may become friends with people that you would have picked out in your pre-kid life, and you may become friends out of default, but either way it is a happy event.
Also on fear of picking the wrong place, normal to be fearful, but only in foresight. Suffolk was wrong (at the time) for what I do as a profession, and we moved when my older one was going into 1st grade. He is more shy than younger one, but loves school, has friends, including a close one that lives about 150 feet away on a straight line, and is well adjusted. I would recommend trying to pick a place before K, but it is very doable to move again after that. I would, of course, avoid serially moving. Even if our current house gets too small for us, I don't want to move again until the kids are in college (a mountain place is another story : ) ).
