Yes, the birder you were with most likely left Michigan before I started birding. Unless it was Hal Cohen, I don't know him.
Hahaha I can picture that scene at WPBO; that serious birder probably didn't think it was so funny though.

Glad you redeemed yourself later!
I've actually never been to Whitefish during landbird migration. Always waterfowl and raptor, so the Spruce Grouse (my specialty! I can find them really well...) are easier to find.
Shorebird migration is just starting to pick up here. Someone saw an American Avocet the other day, as well as 4 Brown Pelicans (GOOD bird for Michigan; but the second time they've been observed in my county this year!)
