I have one of these that I wear on my pin lanyard. Beware! People will constantly ask you questions about the park that you are in...(I have heard stories of people getting mad when you don't know an answer, but this has never happened to me). It's funny...there are usually four of us that travel and wear these, but I am usually the person that people approach with questions!

Also, the SM's will sometimes call you by name when you are waering these...caught me off guard at first!
Have fun!
