The marinas are around the various San Francisco Bay outlets/inlets ..where boats are docked, too. I am probably thinking of a different beast than you are, JETZEN.
The "squirrels" around the marinas are in ground dwellings ..random holes, tunnels, etc. ..and I've never seen any snakes nearby ..in 20+ years here... but I see a few little Western Fence Lizards on occasion.
There's probably a different "ground squirrel" up in the Grass Valley Loop ..which is where Rex was first discovered ..when he was a really young juvenile. That region of trails isn't exactly mountainous ..more hill'y than mountain'y. (Don't ya just love my technical banter?

)
When it warms up, I'm definitely going to do some more herping. Of late, I've just been going up and looking for various arachnids ...I like "bugs" too, y'see? LOL I think I can get hubby to accompany me for some herping now ..I've been working on him some. He's even been to his first reptile show! Took me 10 years or so.. but he'll stay in the same room when someone is out, too.
