I've packed out a lot of elk with a frame pack. Last year I shot a cow 300 yards up hill from a main road and tried out my new game cart . I cut the cow in half and made two trips. That was a pain in the but, the cart would flip over on ANY uneven ground. It took me and my ten year old daughter four hours to get that elk out. After that pack out I'm going back to a frame pack all the way.
