The Great River Road
The Great River Road is a bit of a misnomer for it isn’t a single road. Rather many different roads commingle along a common theme, tracing a route along the Mississippi River. This scenic designation runs contiguously through ten of the United States. By extension it also enters two Canadian Provinces, a total length of…

The Triple Frontier
Twelve Mile Circle reader “jlumsden” returned from vacation in South America recently and sent a couple of photographs. He visited an area called the Triple Frontier, or La Triple Frontera in Spanish or Tríplice Fronteira in Portuguese. It’s the place where Argentina, Brazil and Paraguay come together at a common spot, an international tripoint. So…

Greatest Time Zone Jump
People seem more interested in time zone anomalies than many other quirks I discuss. I know this because I get lots of random one-time visitors to the Twelve Mile Circle via search engines. Invariably they are searching these kinds of queries. I like them too, but I try not to overwhelm my regular readership with…

Split in Two: St. Martin Parish

Neighboring Iberia Parish jabs straight through the middle of St. Martin and cleaves it into two completely different portions separated by several miles.

Point Roberts – Stranded by an International Border
Point Roberts, Washington cannot be reached by land from the rest of the United States. One must drive first into Canada, curve around Boundary Bay, and then cross the border again to re-enter the United States at this remote corner. The establishment of a border between the United States and Canada along the 49th parallel…

Gambling Banned in Nevada!… (in tiny pockets)
Think of Nevada and the cacophony of Las Vegas springs to mind as a reflex.[1] It’s a familiar refrain that repeats across hundreds of desert towns large and small. Envision a symbiotic intertwining of a state economy and a robust gaming industry. Entire towns have even blossomed simply to entice the residents of stricter states…

Union Jack over the USA
The United Kingdom of Great Britain and Northern Ireland proudly flies the Union Flag, often called the Union Jack. It retains an official or semi-official designation throughout the Commonwealth Realm. Oddly, it also flies over a tiny corner of the United States with the explicit approval of the American government. I’m not talking about Hawaii…
