This is one of 6 caches and a bonus adventure lab cache placed along the Berlin river walk. The river walk can be busy at times so you will have to be in stealth mode. There is lots of parking on Maine St near cache. This should be a quick park and grab if not muggles around. You are looking for a magnetic black bison.
