I'm not there yet, but I will be in another four or five months! We're moving from New Hampshire in the Fall.
What makes you say it isn't a very "crunchy" place? Is there gratuitous use of plastic and styrofoam? A scarcity of natural food shops? Is it people's attitudes toward environmental concerns?
Should I be afraid?
I'm on the Reno Natural Mothers group, and they are very friendly. More into the early-childhood issues -- doulas, breastfeeding, cloth diapering, etc. -- than I am, as our only child is almost ten, but still very nice. I look forward to meeting some of them when we get there. Especially if some of them have older children too.
