Pacoima (hometown of Ritchie Valens) is correct. Specifically, Whiteman Airport.

The apropos-ness between the photo and the death of Ritchie Valens isn't as dramatic as I perhaps implied: just the presence of a small airplane.

Okay ... I didn't say it was easy. The main clue is the accident report from when that specific plane caught a wing on a fence in 1998 while taxiing at Van Nuys airport. The report says the pilot "was attempting to return to his home base at the Whiteman Airport."

The second picture is on the Hansen Dam bike path, which is just a half mile or so from Whiteman airport. The Hansen Dam golf course is off to the right. The slope is the dam itself.

The clue in the third, obviously, is the sign. The grocery store in the background is the Lake View Farm Market, in the Lake View Terrace area, close to the other two locations. Plus, the Zacky Farms truck suggests Southern California at least.
