I live a mile or two south of Madison, Wi. MY town, McFarland NO metal detcting ordinance "Turf protection" ordinance is in effect. Same with Monona which is basically part of Madison but you CAN detect pretty much anywhere IN Madison. Town parks, Right of ways, Beaches, etc etc. Just stop by the parks comission here and pick up a FREE permit. They just make/ask you to read a one page "ethics/rules" sheet and sign it. Basic stuff really. Call your county/city parks comission and ask them.
