For decades, I’ve wanted to build a true scale model of the Solar System on the median strip of I-94 between Eau Claire and Tomah. It would be big enuf for passing motorists to actually see the planets to scale and then travel the proportional distance between them. These guys had the same idea, for the same reasons, but lacked the budget (and the federal authorization) to pull it off at interstate-highway distances, so they did it in the desert
. Nonetheless, it’s probably the very first time anyone on Earth has actually created such a model truly to scale.
If you want to make an apple pie from scratch, you must first create the universe.
— Carl Sagan (1934-1996), American astronomer and science writer
Addendum (Dec. 25):
Mark Hobson informs me that just such a scale model
has existed practically in my own back yard since 2009.
