The de-littering aspect takes up a surprising amount of mental cpu cycles. You're constantly scanning the environment for detritus. I DO photograph interesting or quirky things as I encounter them--when I notice the--but that doesn't seem to be the primary focus of each walk. Plus, the Valley isn't known for it's stunning architecture. 😜

(The wealthier parts of the Valley--in the hills south of Ventura Blvd, for example--there are a lot of really interesting (and gaudy and ridiculous-looking) homes. There is also a LOT less trash, so it can be a more aesthetic experience. I like doing those neighborhoods early on Sunday mornings when everything is quiet and there is almost no traffic.)

I've encountered a gentlemen online that is walking different areas of the greater L.A. area and taking many interesting photos--but it's hard to de-trash AND photograph and get thru the planned route in a timely manner.
