Checking in from California

[Curious Joel]

Hey, everyone. I'm with my family in San Francisco to attend my cousin's wedding. We flew in on Thursday. That night we walked up Nob Hill and had dinner at a great Japanese restaurant. Friday, we went to the Wells Fargo Museum, walked past the Transamerica Pyramid, and then climbed Telegraph Hill. After that we had lunch at an italian restaurant off the Embarcadero, then walked down to Fisherman's Wharf. We had dinner at the Equinox, a revolving restaurant on top of the Hyatt. It was fun. Today we went back to Fisherman's Wharf to see about going to Alcatraz, but the boats were full.. Instead we watched the sea lions for a while and then had lunch. After that we took a cab to the Presidio. Then we walked across the Golden Gate Bridge. I have to say that was one of the most amazing experiences of my life! The weather is great.. It's about 65 degrees and sunny.. The view of the city was incredible. Those of you who live in the Bay Area are very lucky! It's great out here.
I have kind of a random question... I noticed at the toll plazas, CA has FasTrak, like the E-ZPass back home. I've seen two different shaped transponders though.. One is a square and one is sort of rectangular.. What's the difference?
Anyway, this is an awesome city.. It's BMW central! Practically every other car is a BMW or Mercedes.. I saw a black brand-new M5 here.. Plenty of 6-series, 5-series, etc..
