No doubt that the price of hunting is going up, but it's still an excellent deal in most places. Compare it to the prices you pay for other things, gas, for example, or your bow(s) or hunting clothes, etc.
Most game departments are strapped for funds, and most rely heavily on license fees for revenue. They have little choice but to raise license fees now and then. Now, some states do sock it to non-residents pretty good, but residents pay low or modest fees in most cases. Even the non-resident license fees, when you compare them to all of the other costs of doing such a hunt, aren't terribly out of line.
