Was a quite frequent saying my father always told me growing up, which has turned into fruition. I used to loose EVERYTHING, and still do
I guess the only things that come to mind I have either lost or forgot to bring on the trail are..
Well 2 trips ago I drove 30 miles down i40 before I remembered my hiking shoes were still in the garage..
Lost my tent at a creek crossing in Big south fork one time.. walked 2 miles back to retrieve it.(It was still dry)
Of course my eating utensil a time or 20...I always bring a set of chopsticks, thus when someone says "shucks I forgot my spork" I say.."I got ya"
