Well we set our own rules. You can put on tandy yellow skins, get some blue speckle ware, a 22 foot tipi with a painted design on the side, and be hc for 1975 rendezvous period.
When its wet and cold, and your bone tired on a trek, and you realize the gray in your beard means you aint a spring chicken no more, and you just cant catch a spark, and no ones around, can you dig a hidden bic out of your bag? May be hide a subway sandwich in your market wallet, to eat when you just finished setting up camp at an event and you don't feel like cooking?
Nobody is 'wrong' for not trying to be as hc as they can. The boys that started the NMLRA just wanted to have fun shooting old guns. All the other chips just fell in to place. Wow I got a powder horn, you don't have to have one, its just fun. Pretty soon you got you a fringed leather 'possibles' bag (that's what they called them then) Then you started saying shooting bag. Pretty soon your neck deep in old style play pretties.
Then along comes the problems with hc. Cast iron was known, but heavy. You think a lot of boys on the trail carrered one. Well you want to be hc get you a tin pot...but you cant bake bread in a tin pot, so get you a tin reflector oven....you think boys on the trail had one of them??? might as well get you a iron pot. After all Plumb-Martin had one, till he tossed it down a hill.
Candle lantrens, I just don't think Bridger had one, or Kenton, but I would bet you could find them at Bents place or at the Alamo. Are they hc? We live in th here and now and from a-e we compromise.
