Excellent stuff! Ken had me cracking up! All too true at times. To become proficient with knots, you need to tie them at least monthly, preferably weekly. We use almost all of those and a few more here at work. It really shows when we haven't trained on them for a while.
I know a really fast way to tie the bowlin, one hand, but I wold never be able to put it in writing......I could show ya. LOL
Now go practice! :D
