Mt. biking solo in VT forrest: Bear cubs. Real cute ones... and they looked scared but I looked even more scared. You know Momma Bear must have been nearby.

Also in woods near a busy highway: Baby Fawn it was heading right for the road (!) walked right by me.. I was stopped at the time and off the bike. Picked it up and turned it around like you do with a crawling baby, and it headed back into the forrest..
Then I saw Mom and she was pissed at me. Take care of your own kids I said...
