Bobcat - I agree completely. The average Joe that goes hunting with a six pack of beer in his backpack is likely not going to check the regs more than once, and certainly not on the WDFW website. As you noted, it really does have an effect on the participation of the handicapped and senior hunters as well. Perhaps we should send up your idea to El Presidente del WDFW for consideration.
I'm not real big in trusting the government to do the right thing in all cases. I wonder in a situation like this, with all these islands being omitted in the hard copy of the regs, whether WDFW hopes to limit the numbers of hunters in areas where they get a lot of complaints from homeowners about hunters "ruining the tranquility of their lovely island". Even though WDFW eventually goes back and make corrections, I'd guess they probably loose 30 - 50% of the number of hunters who might hunt or at least hunt that particular GMU, by making that "inadvertent mistake". Result: fewer complaints and yet completely absolved of mis-deeds by having corrected the mistake online.
I'm a bit cynical (as I'm sure many of you are as well), but I was an Officer in the Navy for nearly 24 years, so I trust my judgement. Often times, government works in the shadows to obtain desired results.
