I spent six months in the Santa Cruz area and for much of the time all I had was a bike. I was impressed with the bike lanes (NONE of those back home) and the motorists' respect for them and bicycle traffic in general. No road rage incidents I recall.
This flatlander viewed the hills as challenges. It wasn't long before I had the best quads of my life! Sadly, they're gone again. "Use it or lose it" is real. :/
Speaking of get-togethers, the weekly car "meets" at the local grocery parking lot in Cali BLEW MY MIND. The hardware there is a gearhead's dream. Truly the epicenter of hot rodding and car customizing, and even complete fabrication!
