I'm with Leonore--weekdays are not so good, but most weekends are. LA, how about posting a heads-up if you have specific plans for shooting; I know I need a couple of days to get the ducks in a row but I'd definitely be up for a walkabout/photo shoot.
I have a 30 day list of all the places I want to shoot, and I keep a rolling 7 day schedule. It's the Project Manager in me - I am too use to Agile and running weekly Sprints
