These skunk streaks are probably the reason I don't do big volume. If I had to search and dump a double-digit number of boxes per week (or even a high-single digit number) and pull one 40% or a skunk I would quit. Doing a small number of boxes and spreading them out makes it less painful, IMHO. The flip side is that I stack much less than some of the big volume searchers here. To each his/her own. My last three boxes have produced a total of 10 keepers (all 40% but 2). This is above average for me and keeps me coming back for more, but with these numbers I don't exactly need to worry about silver storage.
