The law seems to have more to do with your own due diligence to be looking for, and aware, of the posted sign than for them to make it a "slap you across the face" sort of encounter. There can be a perfectly legal sign posted on the entrance door, and people are going to miss it for whatever reason (and we wonder why people wander around in condition white). You can not use missing a posted sign as an excuse unless it is truly blocked from view. It is like trying to get out of a speeding ticket because you did not notice the sign that changed the speed limit from 70 to 35.
