One thing that helps, but is not fool proof. Is that when you get to a site, you may notice that a certain ID number say 62 for example is always the same type of pull tabs in that area for example. That means the chances of 62 is one of those pull tabs and not gold.... most likely....probably,,,,,but it still might be gold. It’s all odds or percentages, how you look at it. But,,, they say, you got to hit the stray ‘strange’ pull tabs some times to increase your odds of gold. HH
