Well, if there's anywhere in America you'd find girls as furry as the French, Cali would be the place to look. ;-)
You might find those furry girls you seek in the areas of California near a liberal University. Probably the same in your state.
Might find a few authentic French girls in Calistoga at the mud baths. The French love those mud baths.
I disagree with one point. UC-Berkley et al., may contribute significantly to the Furry factor in CA but Ithaca, NY most certainly has the lead in per-capita furry American women.
I don't know about places like Berkley, but in Southern California you'd be hard pressed to find a single female who doesn't shave her armpits.
