I ride trees solo a lot, but stay away from anything that looks like a small tree sticking up out of the snow. I try to ride in glades of old growth where all of the branches are way above the snow level and avoid areas that have a lot of second generation and new growth trees.
Good tip, I never knew that. I ride trees solo a lot also and hope to never find this out the hard way. Was this true for you other guys? Was it smaller trees with branches close to the ground?
