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.
Sorry: bit too preoccupied saving my skin to take pics. Garden-variety black bears are one thing, but a mother grizzly with cubs is a whole different risk paradigm.
