welcome to treasure net. the best place is your parks and schools to start out, but watch out for county parks some may ask you for a permit but around me i havent had that problem.... go to your local libray and go to your local history and look at there old maps.. that would be your best bet to start off... try and learn your machine would be a great idea as well i had to learn the hard way and i still have to go back to old places i went becuse i couldnt understand my machine....your county does have a lot of history...
have fun
