This is cache #2, you are looking for a simple light grab cache at the outside of a parking lot of an extremely busy mall.
The Chewy Challenge consists of various cache types that will challenge cachers to use different skills to advance to the next stages. This is meant to be an urban challenge so it is more a test of the brain rather than the body (for the most part 
). The various caches will all lead up to the final bonus cache. The path to the final cache is not a linear one, and you will need to be multi-talented to have a chance at it. Cachers who find the final cache will go down in the Chewy hall of fame and are elidgble to download the highly coveted chewy medal!
Pay attention to ALL cache types to look for any information that might be out there in aiding you information to find the final. Not all caches will help, but they will make you one step closer to being a brainy geocacher.
Best of luck and Happy Caching.
