This will be really Great Greg. What is the filter picking up on, or criteria for a shore dive? I listed 4 shore dives in West Michigan last week (Daisy Day, Helen, Hamlin Lake Dam, Ludington Boat Launch), and there is another inland lake already listed (West Lake) - But None come up in a 100 mile search for shore dives from zip code 49437 (Montague) or 49442 (Muskegon). All listed dive sites are within 50 to 60 miles of these zip codes.
Just tryin’ to help work out the bugs...
