Hey Brooklyn,
If you're new to detecting, I would start off at the local city parks. Find the play grounds that kids like to play in and you'll have more targets than you care to dig, you might even find gold. Once you get the hang of it and you want to do some relic hunting, start reading up un Lexington's history and checkout goggle earth. You will see more old roads and crossroads then you can shake a stick at. Then you will have to get the nerve up and start asking permission to hunt on those properties. Also check out the local swimming holes.
There are more sights out there than you realize. Just hop into your car and start driving around and you'll see them.
I hope this helps.
