There is a song called Hotel California by a band called The Eagles. Hotel California is actually in San Jose Del Cabo, Baja California Sur, Mexico. It is not in California USA. It is in Baja California in the country of Mexico. Baja California is attached to California, USA, but is a different country. 

Drought. We sometimes have drought, but not usually.

Beaches: California beaches are mostly clean. Americans do not accept beaches filled with trash. If an American sees someone littering, they will scold that person. In the tourist areas, a tractor scraps the beach every night to rid it of garbage and seaweed. 

California attire: Californians usually dress casually, but turtleneck shirts are not very common unless you live in the mountains. The winters are cold everywhere, but  often the weather will warm up for a week in the middle of winter and everyone wears short pants, then it gets cold again.

Price: Most of California is extremely expensive, but worth it because of the great weather. If you live north of Sacramento, the prices are much cheaper. I need about $3000 USD per month in wages to survive in Sacramento, California. In San Francisco you need about $5000.
