My grandma lives in Mendocino, and in order for me to see her, I need to cross either the Golden Gate Bridge, or the Bay Bridge. I took the GG on my way there (no toll in that direction) and on my way back, I took the Bay Bridge (no toll that way).
Result ? More cash in my pocket.
I was holding the camera while I was driving. I didn't pay too much attention to how it looked because I had to focus on the road. So I just held it up and hoped for the best.
