It's Porsche country where I live in Maryland. I usually see one Boxser a day, more on weekends. I see about 2 911 per each Boxster. Curiously, Boxster S are rare. I'd say 90% are plain Boxsters. We always signal each other or flash the high beams, like a brotherhood.
I was just in Vancouver, BC for five days. During that time I didn't see a single 987, but i saw about ten 986 on the roads. Also saw one 360 Spyder and a 430 Spyder.
