I think that's more lots of people living in close quarters, houses attached to one another, older houses. Rodents will survive in any climate.

True, although you're wrong about the frost thing. It happens in the early morning sometimes when we have cold weather. I've seen it in my yard probably half a dozen times so far this year. I'm sure it's probably pretty light frost though. It melts within an hour or two.

Serious? How cold does it have to be to get frost, thought it would have to be damn near 32 degrees. It is really rare to see overnight lows dip into the 30s for the city.

I know, right, doesn't NYC have the worst rodent problem even though it freakin' snows there.

Are you sure it isn't dew rather than frost? It's certainly conceivable that frost can form in some areas of San Francisco [low valley region\ bottom of a hill] but highly unlikely. Frost normally needs at least 32F but can form even if it is a little warmer [ie. 33-35F]. San Francisco has a 365-day growing season & has less likelihood of frost than even So Florida due to a variety of geographic factors. When California experienced a freeze in 1990 & again in 2007 San Francisco [like Los Angeles & San Diego] did not record sub-freezing temps.

^I guess it's possible that the specific area where I live (on the edge of Noe Valley/Twin Peaks, and an elevation of 600-700 feet i'd say) occasionally gets low enough temperatures, briefly in the early morning, to create frost. It likes to accumulate on wooden surfaces more than anything else (such as the back deck/stairs), and if you're not careful you can slip and fall on your ass. I'll take a picture next time I see it, and post it...though from the looks of the weather lately that's not likely to be very soon, heh.

We get temps in the low-mid 30s nearly every winter, and I've seen it drop into the 20s on the Peninsula... but I doubt that ever happens in SF proper. Can you imagine driving up these hills in ice/snow?? Yikes.

P.S. Was the town you visited Eureka?
