Cache the Dragon Geocoin Nickel finish. The Tail of the Dragon at Deals Gap, NC with 318 curves in 11 miles, is America’s number one motorcycle and sports car road. After visiting the area, I was inspired to create this unique coin for this truly amazig road. This coin is 1.75" x 1.66" 3mm thick, and has its own icon, which is my logo for ecrater. These coins are trackble at www.geocaching.com and are unactivated.
