In celebration of Denver, Colorado 4/20 Cannabis Cup, River Rock has created this Augmented Reality app. This FREE app allows you to take part in the festivities in Denver April 19th and 20th, 2014 like never before. First download the app. When launched, the camera will appear. When you see our River Rock logo on any sign, sticker, booth or t-shirt, simply hold the camera directly over our logo and watch as our video magically appears. The video will explain all the offerings of River Rock and serve as a guide to your 4/20 Denver Cannabis Cup 2014 experience!
