PS,
I know what you mean when you refer to those areas just littered with bottle caps and pull tabs. I've got to admit, I sometimes avoid those areas to avoid headaches! As have others, and that's why you found the quarter and others hadn't.
TF and I have been hunting this particular place in the woods for about...five months now. When I first started hunting there, I knew about the stories of guys detecting there for years, cleaning the place up. Sometimes certain guys will say things to you to keep you out of "their" areas. Or maybe they really thought it was hunted out...which doesn't say much for their detecting skills/strategy. Whatever the case may be, it has proven to be a great place to find oldies, complete with poison ivy, stickies (burrs), thorn shrubs, mosquitoes, ticks, and all the good things that come with hunting in the thickets!
Good luck on your hunt today.
Joe
