Re: Birch Bark
There are birch trees in Colorado.
IIRC, they don't have the strongest root systems and are prone to falling over. This might make it easier to find a "donor".
My next door neighbors lost a big one this spring. My dad has a big one looming menacingly over the back of his house. If we finally get off our asses and do something about it sometime soon, I will make sure to save you some bark.
