John,

Yes, that was at Logan, back when all there was in the distance was a 100, and 300 yard berm--and two wood benches.

He was always there early in the morning--about the same time I would go in order to beat the wind, which often came up about 11:00 am.

I often wanted to visit with him, to see what new creation he had along. Really interesting guy, because he was different than all the other shooter's out there. I would estimate that he would have been about 75 years of age at that time. Fun times!!

all learning is like a funnel:
however, contrary to popular thought, one begins with the the narrow end.
the more you progress, the more it expands into greater discovery--and the less of an audience you will have...
