On day six of our Southern Arizona Tour we explored Nogales, Rio Rico, Tumacacori, Tubac, Amado, and part of Green Valley. This area of the Santa Cruz River valley is where our home is located. We even took some of our Leisure Travel Van friends to see our home nestled in the foothills of the San Cayetano Mountains here in Rio Rico.
Some of the attractions we visited in this area of southern Arizona: The border wall in Nogales, the Santa Cruz Chili factory, Tumacacori National Historic Park, Tubac Presidio State Historic Park, and the Titan Missile Museum in Green Valley.
Most of the photos shared in this post were donated from the people of our tour group.
There are two stories that explain how Interstate 19 became the only interstate highway in America that uses kilometers instead of miles:
Story number one – In the early1980’s congress was considering changing the U.S. to the metric system. It seemed like a done deal at the time, so in preparation for the change, congress chose Interstate 19 in southern Arizona to be the first to change over to the metric system. However, when it was all said and done, the plan to switch to the metric system was abandoned and Interstate 19 was left as it currently is today, measured in kilometers instead of miles.
Story number two – President Carter wanted to make the visitors from Mexico feel welcome so he ordered Interstate 19 to be changed to kilometers.
I will neither confirm or deny either of these stories. You will have to decide which one to believe. However, apparently the second story is actually the “official” story. Personally, I prefer the first story and I’m sticking to it…
We have lived in this area since 2002. We bought our Leisure Travel Van in 2018 and have traveled in it over 67,000 miles, seen 44 U.S. states including Alaska, 8 Canadian Provinces including Newfoundland, and still love coming home to southern Arizona to witness the beauty of our own backyard… Next post – Buenos Aires National Wildlife Refuge.
