In mid-August, I will be at a conference in the San Francisco area and
want to take a few days to collect landsnails.  Does anyone know of
specific localities where I would be likely to find native snails
(Heminthoglyptas, et al)?  The alternative (exploring every likely
canyon, turning over every likely rock, digging in every potential rock
slide) is a little more time consuming than I can afford on this trip.

Locations in Alameda, Contra Costa, Marin, Monterey, Napa, San
Francisco, San Mateo, Santa Clara, Santa Cruz, Solano, and Sonoma
Counties could be of use to me.

Any information will be really appreciated.

Thanks,
