The Sierra's ARE mountains, lol! They're also a brewing company, ha ha.
Fall is probably the best weather for clothing, imo. Yes, tight sweaters! :P Btw, did you see that Belgar made more tight sweaters?
Yup! Not all of it, but most of it, if I'm not mistaken. Never been there, myself, being mostly a Northern Cali guy.
If it's a beach, with sand, and a large body of water, that's close enough in my book! :D But if it's gross... not so much. ._. There are some nice lakes, around here, but yeah not all of them are exactly glorious. Good for the fishermen, I suppose.
Tornadoes are extremely rare in California, but they do happen. Even if they do show up, they rarely touch down for terribly long. Hurricanes don't reach us, not the right climate for it. (Kinda like tornadoes) People who live in Florida are insane, so much shit to worry about!
Earthquakes? Eh... Unfortunately, we're the state most known for them, being along that "Ring of Fire", or whatever it's called. (No, not the Johnny Cash song, lol! Just looked it up... yup, that's what it is.) Where I live, we're not really in danger of the fault-lines, so that's more down South or by the bay area. (San Francisco, etc.)
