Hunting license for GS shooting in CA?

As cold as it's been off and on the past two, three or four weeks up here in Nor Cal, I wouldn't expect to see too many digger squirrels out and about. It's been rainy and then it clears and gets cold, below freezing. It's been doing this for a while. Not trying to be a bummer, just making you aware of what you might encounter when you get here so you're not negatively surprised. If it warms up, you might get lucky!
