I don't have the words to express how sorry I am to hear that, John. Thank you for passing on the news, even though it's sad.
We all owe Dave a huge debt of gratitude for all the good things he's done for us here in this forum, and for shotgunning in general. I envy those fortunate folks who had the chance to get in a session of Claybusting 101 with him at PGC.
God bless you, Dave, and your family.
