So...I didn't remember if it was on my way to or from work, but I used to notice there was a billboard for Disneyland's Halloween time stuff...
Not really paying attention, I noticed they had the new Disneyland holiday billboard up...then I payed attention enough to realize that the holiday one is on my way to work...and on the back of the SAME billboard...the Halloween poster is still up!

I just thought it was interesting they left that up there when they put up the holiday one on the same structure.
