Hey, last night I was riding to something from SF to Palo Alto.
On I280, just north of the Eastmoor exit, I saw an animal carrier flip off the back of a pickup, looked like just a blanket in there, but couldn't be sure. In any case, the thing was a big hazard.
(I lacked the presence of mind to get the license number.)
Tried calling CHP, phone service failed, but text message to Twitter followers worked (on second try.)
People responded by calling CHP.
We caught up with the guy, tried to let him know something was wrong.
I don't know the results, but the folks who responded deserve lots of credit.
