This is so cool. I'm taking my kids on a road trip around the west soon. Does anyone know of other cool, historical things like this we could hunt for?

I don't get it. Doesn't concrete crack and break in a messy way? How could it be re-used?
> How could it be re-used? To somewhat over-simplify, concrete is made from three things: Cement, large aggregate (big rocks), and small aggregate (little rocks). Broken up concrete works pretty well as large aggregate.
Awesome, thanks!

#43I wonder what semi permanent structures we are building now that future generations will be looking at in 80+ years and wondering about our archaic technology.
Gas stations?

My understanding is that it is an acronym. Fucked Up, Got Ambushed, Zipped In.
My understanding is that acronym stories like that are almost always apocryphal.

#45Even modern pilots (without GPS) use rivers and highways. Why couldn't 1920s pilots use railroads?
It was often hard to tell these features apart from up in the air. There are many instances of pilots losing races because they followed the wrong rail line. For a really in-depth history of pre-electronic navigation, check out "Most Probable Position" by Wright,

The waste water storage tanks at the Fukushima nuclear plant will probably still be around and contaminated 80 years from now. Although I suspect that isn't exactly what you had in mind.
Just fill them with grain and have the birds eat it all. Problem gone.
If the problem was "How can I spread radiation throughout the environment?"

#48A Google Maps collection of these. https://maps.google.com/maps/ms?source=gplus-ogsb&ie=UTF8&oe...
Any particular reason most of the locations on that map are in the West?

#50The link at the end to concrete recycling is fascinating - having demolished 100 ton of concrete and steel in the back yard in the last year, it sounds great to have a largely mess free system.
Unfortunately, it's a student design concept, not an actual product. (This means there are likely to be major functional flaws in the design, as feasibility is generally not a consideration in these design competitions.)
