Don't feel bad, John! I was able to do basic stuff, but I needed Dave's help to make flex track connection snip work right and to get the elevation tool to work at all. I think Dave has made SCARM a sub-hobby and is really good at it. I am so thankful he was so knowledgeable and willing to help me.
I propose the theory that Dave gets a huge supply of Vitamin D living in the Phoenix suburbs, while everyone knows those of us in Western Pennsylvania have a huge Vitamin D deficiency! That's my story, and I'm sticking to it!!
