I'm Pleased to see that neither of you were hurt ! I have collected a pheasant in the same part of my truck before, but with no dammage ..smaller bird, slower speed. But between the wife and I, we have harvested 4 deer over the years, and they did enough damage. I don't envy my family members who live in Alaska, moose are a bit tougher yet.
On that downed eagle..if you are out hunting or driving and come upon a dead bald eagle, you should report it to authorities, and DON'T TOUCH IT ! I guess it's your choice whether to report it or not...but NO SOUVENIRS !! Being caught with a bald eagle feather costs $5,000 and puts you on the "suspect list" with some authorities.
