yup has happened to me too, think its just a part of being new to the hobby and being stuck to parks. I havent had any luck with private property owners and have been turned down very rudely in all but 1 place, which my luck be had was too overgrown to do anything lol. So now i just go a few times a week to the park and not for long. Im in the land of not sure what to do anymore. Best way to explain it is having a hobby you love doing, but cant do it because of things beyond your control. Really sucks. But i do got something to look forward to. We are moving to colorado in march, so i can supplement my metal detecting, to detecting old panning and gold rush sites while also panning for gold, or do a lil of both at different times here and there. Cant wait either, colorado land is alot more public in alot of areas now owned by the bureau of land management and they welcome the public
