On Facebook, SR colleague Joe Butler, who was wandering through Illinois at the time, mentioned that he has gone through a toll booth for the first time in his life and he's seen fireflies for the first time. He prefers fireflies to toll booths any day. Now, I've visited a toll booth or two in bygone days, in California. But I've never seen a firefly.

Question: What is something that you've never seen or done that is fairly common place elsewhere in the United States?
