Now that is one interesting read about some of L.A. Streets from a century ago.
San Vicente, Venice, and La Brea are some of the streets mentioned here.
I just have to add that Nathan Masters has a great series of articles on LA history here on the KCET site as well as on http://southland.gizmodo.com. Much of his stuff would be very interesting to the readers here. I try to follow his columns regularly.
I especially like the article(s) about the hill and tunnel removals near the location pf the current Santa Ana downtown.
