The next 5
1 - Bee hives, the type bee keepers use. I am sure we have all seen them around.
2 - A "wrong way" or "do not enter" road sign
3 - An American Legion post or foreign equivalent.
4 - A truck scale / weigh station . I am assuming they have the same thing in other countries. If not, let me know.
5 - An Observatory.
