I carry a first aid kit and a nurse of 45 plus years on the trails we lead. Most likely the worst we will see is altitude sickness. But all should be prepared to take basic medical care of them selves. Remember to keep the kids slowed down. when jumping out of the truck to look at the flowers. Have had several slight sprains. Recommend a ankle high boot for all if possible. NO FLIP FLOPS on Black Bear, either kind.
