I've just gotta vent here...
This weekend on Baden-Powell I couldn't help but notice the numerous trails directly down the mountain. Following the established (mapped) trail I lost count at around 16 switchbacks. As I hiked along I saw a couple running down the fall line with no regard for the trail. Unfortunately they were too far ahead for me to say something reasonably politely. Being by myself I did not care for a fight.
If you're not going to cause damage (like with snow cover) that's one thing but on popular routes trails are built and maintained for a reason!
