While hiking, I routinely go over, under, and around many fallen trees. This one, however, foils every attempt. There's really thick brush so going around it is out. It's too high to crawl over. And it's too low to crawl under while wearing my pack. I fight with this stupid tree every time I go hiking. Today, I crawled under and my pack got completely stuck. I wriggled and twisted my way loose and fell right over. Fortunately I was annoyed rather than injured. And fortunately, no one else watched me do what was surely a hilarious series of stunts.
On the way back, I took off my pack and crawled under without any problems. I may be slow, but I can be taught.
