Montfort drove around photographing all the addresses. Something I had always meant to do, until I saw that Sounse had already done it in one of his books. Though the quality of the pictures isn't great.
I work a few blocks from his boyhood home on Longwood, but have never driven by. Just a couple of days ago I drove by the second DeLongpre address (5124) for the first time. The court is still there, though a lot has gone up around it. It probably won't be there for long. I think it was a bit of a shithole when he lived there in the 70's and it doesn't look like the landlord has put more than a few hundred dollars into it since then. So you can imagine.
Judging by google satellite maps it looks like the Mariposa address has been redeveloped into some large building. The apartment he lived in for a few months on Oxford is still there, and the house in Silverlake that he and Linda King moved into. Looks like the first DeLongpre court has been renovated though...
One day maybe Carol and I will take a photo tour of all the places and photograph what's still there.
