I think that is expensive, but considering 4 tags, two hunters, and a fully guided hunt, not excessively so.
I have seen landowner bull tags (one tag) go for 10K + here in NV.
So, if you figure in the cost of a NR bull tag, cow tag, and hunting license (times 2) =$2150
That is a pretty good chunk of change for the license and tag alone, just for the general draw, with nothing guranteed at all, and you doing the work.
This hunt alone would cost a person from out of state upwards of $5000 total with tags included.
