Those kids will grow up to be all sorts of people, butcher, baker, candlestick maker.
And every one of them will hold dear memories of you helping them build those Kibler rifles. Besides an appreciation for things olden, they will also carry a good work attitude, a "git 'er done" train of thought, and the knowledge that they can accomplish almost anything that they turn their mind to.
All of us appreciate the effort that was put into that class and into those Alaskan kids - and most of us will volunteer to help in any way possible should you decide to do it again.
