I live in Tucson, I have been here for just about over a year now. I just recently sold my E46 M3 and moved up to a 09 E92 M3, bought it off a member from this forum!
Mt. Lemmon is definitely something you dont want to miss.
I am about to be gone for about 6 months or so, but when I get back, we should all get together sometime and ride up there in the near future.
