If you like hiking or running with a brightly colored Buff on your head, beware! I was wearing this one when a hummingbird flew straight into my face! They buzz, so at first I thought it was some kind of giant killer bee. He pecked my head, realized it wasn't a flower, and zoomed off.
Got to stay bear safe, moose safe, elk safe, and now hummingbird safe out here in Colorado. Next time I go to Rocky, I'll wear my black buff with skulls on.
