I'm heading out to Vail Colorado next month and plan to do some hiking and hanging. I can't get anyone in my group to participate, so I'm going alone. I have a few questions for you guys that hike in that area.

1. Do I need to hang my food in a bear bag?
2. Do I need to be concerned about any non-human predators?
3. Is going alone a bad idea?

What else am I missing here? Thanks
