scrapcat, consider this our formal Thank You for placing You Might Be A Geocacher If… #6 (TheGrundalows) (GC575TH). It should have a little bit of everything you love (minus TaGeez, but feel to drag bring him along): a mystery cache in a nice park, in Detroit, centered around quintessential city landmarks - with a Grundalows touch.
Hopefully, other like minded individuals will enjoy this one too!
Cache is not at the posted coordinates, but the Lake Frances Lighthouse is. To locate the cache, project 210 ft at a bearing of 163 degrees from the lighthouse. The final is a gsix5666 style camo'd powerade container hidden in a winter friendly manner.
