The garbage can thing.... I havnt done it and it hasnt happened on my street, but my friend who lives on Wheeler sees it all the time with trash bags put over the hydrants. We always take the bags off and hope the car gets a ticket or towed or better yet a hose through the window

Where I was parked, there was more than enough room and it was clearly visable from the street. Guess the cop didnt think it was 10ft visable though... :(
