"a long street that spans the different oakland neighborhoods"
7th street is a very long street that spans half of oakland. At the west end, you get a spectacular view of the bay bridge from the relatively abandoned docks and i guess what used to be a very industrious part of oakland. Going east, you pass through some of the most economically disadvantaged neighborhoods. That's when you roll up your window and pray you don't get shot. Going further east, you pass through Oakland's Chinatown. It's relatively dirty, but it's very festive during the day, and you get some good eats there. Going further east, it finally ends up in Laney College.
