I've noticed in my country that there are signs off the interstate highway advertising things that are above a hundred miles from the exit, and sometimes they aren't a large attraction. I guess the interstate has slightly more of an excuse to be misleading than a small town though.

Once before I was led by a detour sign into a maze of different streets, and abandoned with no further signs. I think that was a joke too. Your stories with your sister remind me of mine, except I am the little sister.
