I'm up the road from you in Hamilton. There is also a club in Norwood, Tri-State Historical research and recovery that meets once a month I think. Never attended any of thier meetings due to family and work conflicts but did meet a few members I saw swinging last fall down the road from where I live. Not sure if any of them are on the forum or not but it may be something to look into. As much as I'd love to join ya on a hunt it's pretty hard for me to get out with a full time job and 4 kids in sports. I'm lucky to get an hour or 2 on the weekends and then typically early mornings.
I'm right across the river in Northern Kentucky, though I do a lot of detecting in Cincinnati. The parks are detectable if you get a permit! Hit me up sometime and we'll go for a hunt!
Hey I'm in Fairfield just north of Cincinnati. If anyone is interested in meeting up let me know. I've been wanting to try out some of the parks in Cincinnati.
