macsret --
I wouldn't say there is a crime problem. If there are problems, it's from the college students. I got my BA at Cal Poly in 04 and MA in 07 .. and I also work there now .. I feel comfortable walking the campus and city at night (sometimes I'm at my office at 11pm, and I don't feel unsafe). SLO attracts some backpackers/transients-by-choice, but the PD is VERY particular about keeping SLO a family/tourist community. Most of the Cal Poly students will say the SLO PD are #*$&(&#^&#% because the city would rather squash the college students' "fun" than PO the families. For example, SLO had the largest Mardi Gras parade/turnout west of the Mississippi (no kidding). But it got so large, people started climbing buildings, running around naked, etc. The riot police had to come out to calm things down. The families and shop owners royally complained, so the city nixed ANY ANY ANY kind of Mari Gras festivities -- much to the chagrin of the college students. No amount of pleading will bring Mardi Gras back to SLO.
The city is trying VERY HARD to prevent growth and sprawl because people love the community feel.
The biggest complaint about SLO is there isn't anything to "do" at night because shops/restaurants close between 8-9pm. But college students are always walking around in groups at night, so it's very safe because the place isn't deserted. And, like I said, the PD is ALWAYS around -- either on bike or by car.
Asthmatics? As in people with asthma? Well, I don't really know because I don't have asthma. Many people are allergic to the oak trees, and sometimes pollens can be a problem. Public smoking is banned in CA, we don't have a problem with mold (because of the dry conditions), and because SLO is close to the beach, citizens get some really nice breezes. I can be more specific if you want to ask specific questions.
I hope this has been helpful!
