Some, look at the Regs, its specified by area
This.......most areas are designated on the WMA maps, but use caution with those as well because sometimes they change without notice. Couple of years ago we arrived at a WMA in NW Oklahoma and set up camp in the dark in an area that was marked as a camping area on the WMA map. This spot had always been used as a camping area in the past. We were excited that it was still available because it was near the walk in area we wanted to hunt. After an hour or two of work we had the camper all level, food and coolers out, everything set up and ready to go. I walked over to a nearby fenceline to relieve myself and noticed a brand new sign on the fence. "NO CAMPING, WALK IN AREA ONLY" or something to that effect. OOPS! well that explains why it was still available, had to go break the news to my buddy, we broke up camp in the dark, and moved to a different spot, not a fun experience at the time but one we laugh about now.
