Nothing too "weird" but a few nights ago I saw two Acerbis Motocross boots along side the MUP. Notice that I didn't say "pair". Two boots but different models. This was along the MUP running through the San Fernando Valley. Strange place to spot them as there's no road running along side this portion of the route.
And I see it so often now that it no longer can be classified as "weird": drunks pissing on the side of the MUP through Van Nuys (usually around Sepulveda or Van Nuys Blvd.). Disgusting. Usually once or twice a week.
