Have to agree with the above comments. The LPO (Little Pend Oreille National Wildlife Refuge) roads open on April the 15th and camping is allowed at designated areas. Even "dispersed camping" is at designated areas only. Last year there was snow and no turkeys above the 3,000' mark at the start of the season. But the LPO has plenty of open forest below 3,000'. It also has no hunting areas which you can find by using OnX Maps. Note that camping at Starvation Lake can get crowded AND it's a state park with no hunting allowed in the park. One half mile or so down the road is the LPO where you can hunt. Starvation Lake Road ends to the North at Hwy 20 and across the hwy it's nearly all public land all the way to Canada. A lot of it may have snow also. Electronic turkey calls are not allowed in WA.
Bring a chainsaw... might help get thru some roads that are recently snow free but have windfall trees on them.
Also don't be afraid to know on some farmers doors. They do not like turkeys. Good luck.
