I guess I'm an urban transplant myself, being originally from the hellhole of St. Louis. I moved to Colorado way back when until I realized that I had actually moved to CALorado. Talking about the politics, and not necessarily the people of California. Many CO natives are as "Californicated" as the transplants, and good riddance to them all. I live in a trailer and will be building a house, and while the hilltop is where the least amount of snow piles up I have decided against building there for the reason you stated above and just put a road on the ridge instead that turns down the hill at the end... I try to be a good neighbor and I don't complain about the derelict cars in my neighbor's yard; what's his is his to do with as he pleases and besides, they have been a good source of parts for me.
There are 1 or 2 others who don't feel that way and like to scare him (and the rest of us) with threats of an HOA, legal action, etc. but so far it's been nothing but talk, and a vote on an HOA would go down in flames as it should.
I go back to Missouri, see family and friends, and listen to the stories about how they hate this neighbor, how they've lived there for 10 years and never spoken to another, etc., and am glad I live in a place where I not only wave to mine when I drive by, I can and do stop and talk. I'll help them put a roof on their place or whatever and they'll do the same for me. These things are mostly unheard of where I grew up, so I know what you mean when it comes to the urban mentality, and I hope my adopted "neighborhood" never changes. That makes me hesitant to even mention the Pedros in this forum, but growth is inevitable, I guess, and if I tell people about what to expect before they get there we'll all be better off.
