The kids found this guy in our family room earlier in the week. We kept him in a container for a while and today Q & I let him go high up on the hill. I just learned today that our neighbor to the west found one (caught in a spider web in garage) and the neighbors 2 houses to the east have also seen them recently. Not sure why nor if we'll see any more. Apparently this is a native Marin kind of scorpion and its' sting would be similar to a bee sting.
