Motivational? A mother grizzly bear and two cubs waiting alongside the road on my evening commute. Getting around them would have involved a 45 minute detour. I swung over to the opposite side of the road facing traffic and gunned it up to about 30mph. Didn't dare look back for a couple of miles.
I dunno. I've tried to outrun wildlife. I had a deer once that was just determined to pass me and cross the road in front of me. I tried my damnest, but she won the race. The bear I've encountered tend to keep to themselves and stay away from people - and vice versa! Still, I ain't gonna mess with a mom and her cubs. Certainly you get a gold star for motivation - I'm sure your shot of adrenaline kept you pumping pretty hard!!!
