Last year, I specifically targeted small neighborhood "lots" that would be prime spots for years of slow trickle drops. I'd done very well after a couple of months, pulling close to 50 rings, about a half dozen golds, and about 20 silvers.
On a nice 3 day weekend in the summer, I was going from spot to spot, just checking my phone. Day 2 of the weekend, I started in the same neighborhood I'd done the day before, and had pulled several sterling items, and a half-dozen rings. I pulled open my phone and found a park, and went to it. The park was eerily quiet under the coil. I was finding NOTHING. It was hard to believe, since the parks had all been 'full.' So I started looking, and eventually found a small mark that indicated a flap cut. I actually said to myself, "DANG, that MDer digs nice flaps! I can barely see them!" Clearly, the park had been detected not too long ago. It was a complete dud.
Then... Then I realized, "oh, this is the park I hit yesterday, I just drove into it from a different direction, and it looked different when I walked in."
DOH! Dud indeed, I'd already cleaned it out. Ah well, at least my honest-to-goodness review of my own cuts were favorable. LOL
