This only happened when I was early on the way to work and could drive at 30-40 MPH at 10PM to 2AM depending on when I had to commute.
We have had a blue heron follow us for over 10 miles when canoeing on the Connecticut River and loons swimming back and forth under our canoe on lakes and ponds in 3-4 foot deep water.
If you go early on the snowmobile trails you will often see more animal tracks than snowmobile tracks. It is their highway at night.
Were your lights on when the owl was flying with you? I’m curious if it was using the light. Snowys so rarely visit this area...and some a-ho usually shoots it when one does.
