Bill, truly, thank you for the kind words. Pony Express, thank you as well. I don't know if it deserve them but I am inspired to live up to them. All your points are valid. I grew up on DC Beard as well and although there is little you can do on a national park, the best place for this kind of outlet is typically on BLM for light structures and projects and private property for more permanent structures like cabins and watch towers (the latter, I have never made but would like to). Generally, I recommend people stick to learning fire lays, cooking setups, survival shelters and stockaded tents as they are relatively quick and easy to build with a light amount of resources.
To everyone out there, some of us really geek out on the small details but that is just one element of celebrating this Nation's heritage. There was a time when I sneered at the 10-ft rule, then I grew up and came to appreciate the efforts of everyone interested in keeping this hobby alive. Now, I would rather see someone with an "okay" kit at 10-feet and a head full of knowledge than a pompous elitist who thinks his pocket trinkets and intricate small details make him the better man.
If you live in an area where there is not much for reenacting, then show people what you know on times gone by in a setting they can relate to. Light a pipe with your steel once in a while, make a kitchen set and proper fire lay the next time you take the fam and friends camping; or take your muzzle loader to the range and don't be afraid to answer questions. The last time I went shooting, I had a couple of off duty SWAT guys geek out on my long rifles and after hammering out a few shots each, they beamed ear to ear like the kid in them just woke up Christmas morning.
Gentlemen, it is my privilege to have such good company as the likes of you on this site to share ideas with, debate history and learn something new. I don't know if this hobby will ever be a mainstream thing but I am proud to stand with you in the ranks of a unique lineage where the past remains vibrant so that our present lives may be fuller and more meaningful. We are the life blood of this Nations Living Heritage. You are all truly salt of the earth.
