The same thing as some in Walla Walla, I suppose: Growthophobia.
I don't get it. If you have a place worth living in, other people are going to want to live there too. Growth is a compliment, not a cancer. If you don't like growth, the answer is simple. Live in a place so hell-holish, no one else will want to live there.
Do those people opposing growth realize how elitist, selfish and downright HATEFUL it is to try and keep other people from enjoying what they already have?
