Just passing through but wanted to quickly note that your excellent work immediately reminded me of that of fellow Montanan Don Greytak, who I believe has always worked exclusively in pencil. I "discovered" him during a Minnesota camping trip when we ventured into Brookings S.D. for a huge, wonderful annual arts festival. See Greytak's work at:

Back later.
