Cedar, I can't say for sure, but I believe that there are a lot of animals "mistakenly" taken in spike only units as well, or 3 point areas for that matter. Many hunters do pass on 1x2's 1x3's etc. that would otherwise have been taken, and I believe most people will agree that there has been fewer hunters in the true spike areas since the change. The wild card I believe is the native harvest in these areas, has the true spike rule changed that harvest rate? I don't know.
