Also: <a href="https://en.wikipedia.org/wiki/St._Francis_Dam" rel="nofollow">https://en.wikipedia.org/wiki/St._Francis_Dam</a><p>I noticed this:<p>> St. Francis Dam was completed in May, 1926. [...] The dam cost [...] 1,300,000 dollars.<p>These days, in many parts of the U.S., $1.3M wouldn't build you a decent upper-ish class house.<p>100 years from now - will $1.3M even buy you a scoop of ice cream?
