Hi there R & Me! Your mom is in for a treat when she visits San Francisco, it's one of the most beautiful cities ever and a zillion things to do & see. Beautiful views of oceans & hills from all over the city and mountains to the north across the bay. Fantastic. Can't say much about Sacramento, it's northern California but a bit inland and more or less a typical California town (if anything in California can be called typical ). Las Vegas is very glitzy and quite "adult" oriented with gambling, lots of neon lights and glitter and show biz talk, people & hype. Stuck in the middle of the desert it doesn't offer much these days if you're not into the "adult entertainment" thing. Of course others might have totally opposite ideas, that's just my opinion. I'm sure your mom will enjoy her visit to American and I hope she brings you back something very special
