We have not met anyone of questionable character yet. The Hikeboss puts as much information about the trail and conditions on the site as possible. We take well marked trails in state and national parks. Our leaders are not out for any high-adrenaline adventure. A co-leader is assigned to each hike if someone has difficulty and has to go back.
All activities involving height and motion have a risk of injury.
Pack out what you pack in. Stay on the trail and with the group. Stay with someone with a walkie talkie if you do not know the trail. Carry your own water, first aid, food and gear. Know your limitations.
