Calf skin fingerless gloves to ward off thorns from multi-flora rose. They have saved me from many a scratch, I know this because I've regretted everytime I've forgotten them over the years.

Also every once in a while I'll take some black powder loads with me for the heck of it. I bought a couple of boxes of GOEX loaded 7.5's years ago and use them for practical jokes when someone wants to borrow a shell too. grin
