We recently finished a 6 day hike with younger scouts, 3 eleven year olds, 2 twelve year olds, and one 13 y.o. We also had 5 adults, one on her first backpack, one fairly new to backpacking, one with some backpacking experience from years ago, and two with strong backpacking skills. (I put myself in the latter group). The boys proved themselves tough hikers, with no whining, no complaining, and adequate strength to go all day.
We had a pack check, and weighed packs, and looked at boots. We missed one kid, however, regarding his boots. I asked him "are they hiking boots, and do they fit?" Oh yes they are hiking boots and they fit perfectly. The kid, an Indian youth, showed up with hi top insulated winter boots for a 6 mile per day hike in desert sand. They were 1.5 sizes too large. We left those at the car. He did the hike in his street shoes, which were leather shoes with velcro strap closure. We also carried a pair of light trail shoes in case the leather shoes gave way, and they did look very sloppy.
We had one parent, the guy with some backpacking experience, show up with 3 lawn chairs. One for himself, one for the gal on her first backpack, one for his son. His pack weighed appoximately 65 pounds. With no food, mine weighed about 16. He also had a $500 Randall sheath knife on his belt. The gal didn't have any problems, as she was a runner and very sturdy. The kid only carried the lawn chair the first day, then Dad was carrying two lawn chairs. He had a bit of a learning experience, as every bit of gear he had was the heavyweight version, and he had a hard time keeping up with fleet 11 year olds. For example he had a Coleman peak one gas stove (the old pot bellied tank kind), a liter of fuel, a pot set big enough for 8, the kind of oatmeal you cook, Lipton noodle dinners which you boil for 20 minutes, a ski coat, and I don't know what else was in his pack. I ended up carrying a lawn chair for the last half of the trip, and it was nice to have a seat in camp.
Everybody had a good time. Everybody including me learned something. Pics of the trip at
