Nothing too crazy....do try to be prepared though....

by the way, I'm not sure any flatlander can be prepared for 35lb packs at 9000 feet, sure great condition helps, but almost everything I read about altitude is your condition has nothign to do with the fact you may or may not get sick at altitude.....apparently its a genetic lottery who is able to adjust the fastest with change of altitude....

If hunting alone....you should leave some detailed directions/maps, and having a satellite phone isn't a bad idea....or at least a cell phone /extender etc.....
