So here is another question: If collecting a tree with old looking bark is a major contender in your choice of material and trees that fit into that category are not available to you what are your options? The only native North American Pine that has as good a bark as JBP is the Ponderosa Pine.
I never said it had to have bark as good as a JBP. But an old collected jack pine has better bark than any nursery mugo every will, and even better than the centuries-old mugos they pull out of the alps in Europe.
Ever seen pitch pine bark? It can get pretty darn impressive!
Anyway, I vote to end this discussion. Our opinions are clear. Lets post more pictures of trees and talk about something else.
