Tour Guide Hat

Being a tour guide would be fun, but if I had to walk backwards, I would be paranoid about tripping over some misplaced object.  But then, I had an idea.

Bikers can install little rear-view mirrors, so why can't tour guides?  The best way to attach it would obviously be a stylish* tour guide hat.  That way, it is easy to check behind when walking backwards.

Additionally, I decided to attach a speaker and microphone combination, perfect for loud areas, ensuring that the audience can hear the wonderful historical facts about the area.

Side note: Tour guides are the only people who can tell the oldest, worst puns and still get away with it.
