Its probably expected but WMNF has closed down toilet facilities at the majority of the trailheads. It also includes Barnes Field which will make winter camping problematical.

Sadly my guess is folks will still go to these locations and will end up using the woods and many will not be using LNT principles. I do not expect the Cog is an "essential business" so they most likely will not operating. Pinkham is also closed so anyone heading up Washington had better make plans
