This postcard came from friends and neighbors who just returned from the lower 48 (U.S.) states. I collect train postcards and they seem to find the best cards for me.
This card is post dated 1928 and shows the Royal Gorge, Colorado. The gorge's rock walls are some 2,500 feet and not nearly as wide, so the effect of being in the gorge is a little claustrophobic to some.
Traveling the gorge by train is fairly high on my bucket list.
