Then come ride our local trails. They wind through a forest preserve, timber, and wetlands - beautiful scenery, wildlife, etc. But by the middle of summer things can get pretty shaggy, often with brush and low branches reducing the trail to one lane before the crews cut things back.

So - brush hanging over the trail + blind corner + fast oncoming traffic = lost mirror. My options: Hit the other bike head on, run off the trail into the unknown, or duck and run under the low hanging stuff. I went flat on the bar, protecting my face. Seemed like a good choice at the time. The old mirror was a minor loss.

I've had to dodge deer that have jumped out in front of me and swerved around a groundhog or two, but as for running into trees - no experience there.
