It's political correctness at work. If you put natural wonders on a coin, no one can really argue with it, and it makes the enviros happy.
But if you start putting things you are proud of from your history, expect the leftists to come out screaming. Monticello? Jefferson owned slaves! The alamo? Anti-mexican!
Let's not even get into southern plantation buildings or native americans.
this is a conservative columnist. and what HISTORY? a boat and a loon?
The Alamo would have been the perfect image for the Texas quarter, instead of what they chose. I guess the map outlines are selected as inoffensive...but the Louisiana Purchase outline does not have the original boundary of the Louisiana Purchase, but shows the line negotiated by John Quincy Adams in 1819.
Next up: Oregon, Kansas, and West Virginia.
