I would strongly recommend you sit down and read the regulation booklet, at least the part in the front that gives the statewide rules and the sections on areas you plan to fish. There are a lot of regulations on specific waters, especially in regards to where you can and can't use a two pole permit. Most of them have to do with saltwater or rivers, but you absolutely need to know them. There is no statewide limit on crappie, but some waters have size and catch limits.

Just took a peek at the WA regs, and I swear, they get more complicated every year. I miss fishing for salmon and halibut, but I'm glad ID has much simpler regs.
