Amazon has them fairly cheap if you are willing to go with used paperbacks. I had read most of his stuff in F&S over the years. Our school Librarian was discarding "How I got this way". I reread that then went on amazon and picked up 4-5 to reminisce. kind of like hanging out with the guys I grew up with over a glass of Makers Mark. Inevitably one or more of the wives mutters, how the hell are they still all alive with their limbs intact?
Nah. I will be buying the full rack. As it turns out, I was not aware of his continuation... The first boxed set is what I knew... And there's another other boxed set after that, and then some! So I have a happy 'catching up' to look forward to - And it's all your fault.

And yeah, reminisce is right... He's over in Idaho, which is spitting distance around here... So if you rub off the humor, that's my life he's talking about. I lived it too.
like the soapbox airplane and the barn roof... Not quite the same, but we built a long ramp out of snow so we could sled from the top of the barn roof, across the barnyard, down the hill and across the pond...
I experienced that same exhilaration he described, sitting there on the barn peak with my Flexible Flyer... I too came oh-so-close to mishap, though unlike him, I DID complete my run successfully, just the one time, to include not falling off the side of the ramp (ice by that time), and shooting the gap, remembering to duck under the propped up barbed wire, so it only tore the back of my winter coat to shreds, and wholly deprived me of the ass of my pants and underpants, as I shot through at 247 miles an hour... leaving grooves in my butt that the old man could use for measurement as he applied my soon-to-come whoopin.
It seems the roof of the barn was made of tin type... A very thin aluminum cast-off from news-printing back in the day. And it seems a robust young lad, on a Flexible Flyer with sharpened runners, is not considered a warrantable use of a tin type roof, and it turns out, is a mass quite beyond the shear strength of four roofing nails and easily transgresses the mil thickness of the thin aluminum... rending it and rendering it useless as a roofing product - that is, where it did not just tear away altogether.
That is how the barn got a brandy-spankin new corrugated tin roof at top-dollar prices, and I got a brand new parka and pants to cover my freshly paddled butt.
Ah, those were the days, right?
