Short of quitting or buying horses or llamas iam having trouble hiking. I broke my back in 2009 and now it sucks to carry a pack. I have a kuiu and iam sure if I was young and fit it would be great but it just isn't working. I have several old style backpacking packs like an old Dana designs and a north face but was going to see if it was worth trying the new school stuff. I live in Bozeman so I can go see mystery ranch or the other super cool one stone glacier . Is it worth a try or should I move on to greener pastures. I try and hike a 100 miles a summer and we usually do about that during the hunting season but I hurt bad and it's not fun.
