As an Oregon resident who has hunted in Washington for the last 8 years (and was a Washington resident who hunted there for the 20 years prior to that), I gave my input both online and in the public meeting held in Vancouver that I would have liked the Washington regulations printed as early as possible.
Is there the potential for conflict if one is drawn in multiple states with conflicting seasons? Certainly

Would that be a
GREAT problem to have? Absolutely

For those who may not be aware, in Oregon you do not have to pick up a controlled tag that you are drawn for; if for some reason a conflict were to exist, options do exist.
When I draw my moose tag in Washington I likely won't care much about what I have drawn in Oregon that year.

And personally, its quite enjoyable to be planning my Oregon hunts already because the Oregon synopsis has been out since November; the fact that actual tag allocations won't be known until early May doesn't matter much because trends of tag allocations give the hunter an idea of what is likely to be available.
I wish Washington would do the same thing.
