To those of you who posted your support, and anyone else who might be interested, cyberscore finally added these two levels to the KD board :D

I got some help from SloBro's Holy Cow video, but reworked the route, especially at the end, so I could go up to the parking lot, grabbing the last few items on my way to the drop-off on the left. This way you don't have to hunt around the forest, wondering where the heck the Holy Cow is. But I think someone could improve upon my time.

For what it's worth, my basic route for Ursa involved a simple clockwise loop around the main road, grabbing the line of skaters near the top of the hill (you hit them in a straight line, then turn around and get them). After the shrubs and lampposts, I make a hard right into the "bleachers," then through the water and across toward the soda machines and the park. Trees and fence. Bear! :)
