I drew a Woodland Card that says to look at the top 3 cards of the Adventure Deck. Does that mean the Main Adventure Deck, or the Woodland Adventure Deck? I know I've seen a rule for this somewhere, but I don't remember where. I believe that no matter what region you are in, if the card says Adventure Deck, then it means the Main Adventure Deck. Is that right? If the rules wanted you to draw from the Woodland (or Highland, Dungeon, etc) wouldn't it say?

You draw from the deck of the region you are in, so if you drew this woodland card in the woodlands, you would use the woodland deck. You would only use the adventure deck if you drew it while in outer or middle regions.
