I have enjoy searching for "odd" and "unique", not to mention "strange" road signs. These travel signs were found on scenic roads throughout my travel adventures.
Yosemite makes a BIG deal about the bears in the park. They do not allow any food, ice chests, water bottles, granola bars, tick tacks, gum wrappers etc. in the car over night. All items had to be brought up to the hotel room with us....
