Same thing happened to me about 6 months ago or so - referring to the op - There was a tree down going right across the bike path. It wasn't just a little tree either and there was a hill on oneside and the ocean on the other so I couldn't go around it. I had to shoulder my bike with full panniers and climb over the tree. I got over about 3 branches and was able to drop my bike down on the other side and then climb down. It was pretty windy the night before and there was probably termites in there since it was a pretty old tree.
