They probably try to avoid turning these meetings into document reviews, probably to avoid blowing up the agenda while picking apart documents, and possibly to avoid well-prepared opposition to their proposals.

Whatever the case, in my daily work, I am expected to deliver an agenda, complete with links to resources, at least one business day prior to any meeting I organize. I'm sure that's true for internal meetings at WDFW as well, and I think it's reasonable for us to expect that courtesy in public meetings where we're intended to function as stakeholders in a process to which such documents are relevant.
