The above link attests to economic impact of wolves to the YNP gateway communities. It's not my opinion; it's credible analysis. Whatever the dollar amounts are, it does reflect a potential for YNP itself to benefit.
Allow cynicism to doubt the research and analysis of professionals (and there are several other studies as well), but regardless there is potential for positive gains from this wolf debacle. Why continue the rhetoric emphasizing "sides", and dwelling on monies already spent ... water under the bridge. Let's agree to move ahead in some positive way.
