Please DO NOT go to posted coordinates as there is NO CACHE there.
In order to find the cache, you must visit each of the "Urban Cache" cache sites. Each cache may or may not have coordinates for the bonus cache. So keep a look out and don't forget to write the coordinates down.
Good Luck and have fun.
