This year I have encountered several sites that looked good when I got there. No dig holes, iron on rocks... So I put the coil down and end up usually dissapointed and pull out 1-2 buttons, a relic, some shot gun shells and occasionally a stray copper. The strange thing is I've been to other sites this year where I saw a bunch of dig holes and still pulled out more objects. It's gotten me confused. How long do dig holes in the woods usually last on average? There's been a few towns located near each other where it seems almost every site is like this, no dig holes but simply no targets. Most of the sites I'm talking about are colonial and were abandoned prior to the introduction of the maps. Are these sites just "poor" and thus dropped very little or were they hunted 10 years ago? It's been bothering me all year as it seems to Mostly be the case in a select few towns all located near each other.
