I live in Fort Collins, Colorado I see about 4 to 5 WRXs a day. No STIs. When I go visit my brother in Boulder...Man, in ONE trip across town (swinging by the CU campus area) you could probably see more than 10 WRXs. I was there last weekend and saw 3 STis in half an hour. When I first got my WRX I lived in Boulder and found my self annoyed that everyone had the same car as me. Then I realized that they just have good taste, like me.
There are so many Subarus in CO it's not even funny. I think it a good thing!
