The fairgrounds in Golden Colorado are the home of the Westernaires, a demonstration horse riding group that puts on precision horse riding shows at various events including the Denver Rodeo. The Westernaires can often be seen out riding in a nearby show ring with bleachers for fans and families. When the Westernaires are not riding there frequently will be a bunch of horses just across the fence from this cache. If they are out when you come looking for the cache they may come by to see you.
This cache is a medium sized centrifuge tube just hanging around. The fun fact about the centrifuge tube is that one of us was doing analysis of samples for the infamous Solyndra solar cell company so the cache has them to thank for its container.
This should be a pretty easy park and grab. You won't be able to roll up to it in a wheelchair but it should be accessible to those without mobility issues (or with issues then with help to get to GZ) but anyone should be able to get within about 10 feet (3 m) of the cache.
