Fan that comes on at 45-60MPH

This past weekend suddenly had a loud, fan-like rattle start while driving down the freeway. Randomly seemed to coincide with opening the window, but we've further determined that something starts about 45 (for wife) - 60 (for me) and is louder than the normal radio volume. It reminds me of putting a card in my spokes. Was cool back in the day, but not on my 325.

Any ideas on the location of a fan that might match this description? MAYBE it is just a leaf or something stuck in a fan blade
