Well I live in the USA and I'm proud of that fact. But, what are those other flags for?
The next is the Arizona state flag. I was born in Tucson, AZ. Arizona is where I had my first train experiences. My first steam train ride in the cab of #36 on the White Mountain Scenic Railroad.
The third is the Colorado state flag. Colorado is where I grew up and fell in love with the D&RGW and RGS narrow gauge railroads. The Durango & Silverton is in Colorado.
The fourth is the New Mexico state flag. The Cumbres & Toltec starts out in Chama, NM, and as it heads over Cumbres Pass toward Antonito, CO it crosses the Colorado and New Mexico borders several times. The D&RGW also made its way south into New Mexico on its way down to Farmington, NM.
And that's why those flags are there.
