JE...congrats on the silver, and 166 plugs per silver..idk, just depends where you're hunting, like Toasted said, spots can vary in what they produce, my go-to spot is weird...TONS of clad (soccer facility for ten years)...and while it has coughed up a 43 Walker half, a 2? Standing quarter and a ?? Largie...ive only dug one wheat, NO Rosies or Mercs...im not sure if this site was cherry picked long ago, but I know they can't find them all, it's a 15 plus acre plot. But one thing I DO KNOW, JE...is that you cannot over-think this hobby..too many variables on place; past hunters, the addition/removal of dirt, etc..just keep on hunting and dig every solid signal, especially on older sites...nice Rosie!
