Ask Slashdot: Science Sights To See?
First time accepted submitter steevven1 writes "My girlfriend and I are planning a long trip across the United States for this summer, and we'd like to see the usual sights, but we both have a bit of a geeky side, and we were trying to think of science-related marvels to see along the way. So far, we have thought of places like the Very Large Array in New Mexico and Fermilab in Illinois. Any suggestions?"
Near Arco, Idaho, is the site of Experimental Breeder Reactor 1.
"At 1:50 pm on December 20, 1951 it became the world's first electricity-generating nuclear power plant when it produced sufficient electricity to illuminate four 200-watt light bulbs."
It's decommissioned now, but the building and much of the original equipment is still there, along with good museum exhibits.
You haven't said what route you're taking across the States, but Arco is along the "Oregon Trail" as documented in the guidebook "Road Trip USA" (which I thoroughly recommend, having driven four of its cross-country routes)
