Collection of LEO programming sheets

This is stuff that I’ve got and had given notional NAHC numbers in anticipation of it going to NAHC. A lot was collected at the 2010 and 2012 reunions. I’ve also had more stuff since that isn’t on this list but which I am sorting out. All this belongs to the Society as far as I’m concerned and I will take it to CCH.
