I practice my 24 (remember, I'm a newbie) or so knots all week long, but today I got to tie a couple in the wild. I had to tie a stack of lumber to the top of my car. The problem was which of the several anchoring hitches to tie, and then which of the 4 adjustable hitches to use. I went with the classics: buntline to anchor and trucker's hitch with the Alpine butterfly and double half to finish. It was brilliant. All that practice paid off. I condescendingly wondered how many of the folks around me, tying things to their cars, were using legit knots. Anyway, love those real-life opportunities.
