Grew up in Tahoe, I go there multiple times a year for the excellent skiing, beautiful scenery, hiking, biking, and camping. Everyone deserves to see it at least once!
Reno is a great little home base if you're looking for some skiing or gambling.
Traveled to the Grand Sierra Resort in winter. It's a fun weekend from the Bay Area, but not as grand as Vegas.
I love Reno! All of my family lives there and there's so much to do! You can go into casinos, find an ice skating rink during the winter, and eat at a bunch of cool places!
