On my Sycamore Canyon hike, I found some great whimsical trail graffiti on a dumpster lid:

Now, HikingLA ‘s webmistress has located what she describes as “the most good-natured trail graffiti (she’s) ever seen.”

Remember – graffiti is bad. Unless it comes off easily, and doesn’t cover up any important information on man-made signs.

And sometimes, if it makes you smile.
