Came across a mama and 2 cubs while riding home on the local MUP after dark one night last fall. This MUP had opened not long before and I thought the bear family was just some kitschy trailside art when they dimly appeared at the edge of my lights. Then came a "WHUFF?"
Oh crap, they're REAL!
All 3 of them stood, very straight, with my blinking headlight strobing back at me from their eyes in a way that suddenly made me aware of my bowels. It was a Gary Larson cartoon begging for a caption! All 4 of us stared at each other until Mama dropped to all fours and took off up into the trees with her cubs in tow. It was one of the weirdest commuting moments I've ever had.
