According to Wikipedia, rickrolling is a "bait and switch." In the world of the Internet, it involves misleading links that take you to Rick Astley's 1987 music video for "Never Gonna Give You Up." In the case of this cache, you are taking Rick Road to the back "entrance" of Morrison Rockwood State Park (already misleading because many GPS units will tell you this is how you get into the park - NOT!)
Information that may be helpful or misleading: it is a (largish) micro container I received while hunting the Murder Mystery Series (Thanks, Reeser11!); it is magnetic; it could hold small swag or small TBs/geocoins; you cannot access the main parts of Rockwood from this entrance.
Please make sure the camouflage is returned exactly as you found it in order to make every cacher's experience as entertaining as yours!
