I guess I got lucky by emailing the city parks & rec. dept. and actually getting a pos. response..Most everything is illegal in Fl. lately.My letter was as follows; Hello,I have a very simple question that is seemingly impossible to get an answer for,I hope you can help.All i'm trying to find out is,is it legal for me to take my nephew metal detecting in city parks?I've emailed several different sources ,to no avail,I hope you can help.Thier reply was; To the best of my knowledge there is no rule that would prohibit you from using a metal detector in our city parks.Have fun and good luck.PS.,Let us know if you find a lost fortune,we may come out and join you!!! if you have any further questions ,give us a call at(number),(name)assistant director,park,recreation and cultural arts. Do you like how I threw my nephew in there as a pity ploy tactic? HA-HA.Whatever the case it worked and I too carry a copy whenever I hunt the city parks.Sounds like you have it whooped already being friends with the local police and all.Good luck and H.H.
