For the most part it is. If you build a blind on public land or waters, it becomes public and is first come, first served. I believe there is a 4am rule also(meaning you're not allowed to start setting dekes until 4am at the earliest). There are some guides that have fancy blinds in the potholes and they pay a young kid to go out there at 2am and hang a light on their blind and reserve it for their clients, and it's all supposed to be public! Some of the refuges have draw blinds and handicapped accessible blinds that are open to the public, but I've never hunted them. There are a lot of private clubs on the west side and around moses lake, and a lot of public competition, but over here on the east side, not so much. The Moses Lake (Columbia Basin) Area and the area around Tri-Cities (where the Snake and Columbia meet), are by far the most popular (and hold the most birds)in the state, hence the competition.
