Green Frog Productions out of Marietta, GA (1 800 227-1336
[www.greenfrog.com]) has a great selection of abandonment era narrow gauge footage. From their selection, I highly recommend a 90 minute tape called "The Rio Grande Southern and The Denver and Rio Grande Western" which is from the color films of Jack Alexander and Vince Ryan. Included are shots of the Black Canyon of the Gunnison and RGS Geese over Lizard Head pass. Green Frog also has Emery Goolash footage available and I would recommend "The Best of the Narrow Gauge."
