you may leave suitable offerings at the sign and make a little Obama shrine

I think it's probably illegal to leave large quantities of crap in public. We could probably get the dog to take a leak on it, though: "Fido salutes thee!"

LMAO. In the best legislative speak, I failed to identify what may be, but is not limited to, things which are ‘suitable offerings’.

Excrement would definitely qualify as a suitable offering, regardless of illegal dumping restrictions. But if you or your dog craps by a sign and no one is there to hear it fall, does it exist?
