This brings up an "old story" for me as well. I still use my Gerry 20 F mummy that I bought in 1971 at the yearly EMS Sale on Comm Ave. We thumbed in and camped out on the sidewalk. I tried out several bags and the only one I could afford was the regular version even though I really needed the long. It was $15 more and I only had enough for the regular. I finally decided to go with the smaller one and the guy who was helping us out said he'd put the bags away for us while I counted out my money. (I was fifteen and worked all summer out to sea on a fishing boat to scrape up the $80 for the bag). When we got back home and I opened up my bag there was the long bag in the regular stuff sack!
I never got that guy's name but I'll certainly never forget him and I think of him every time I use it. Seriously good Karma in that bag!
