I don't want to plan ahead that much - prefer the spontaneous outings.

so we need a permit to walk in the woods now. What's next?

Your question really needs to address wilderness camping as that activity impacts greatly the wilderness landscape. Day, permits, visits are far less destructive to the Three Sisters Wilderness and easier to obtain.

I'll go out just somewhere else.

We already pay taxes on this land and this adds a spontanious barrier to access. Loicals should be able to go and hike anytime anywhere. Permits can be for visitors

Your already paying for high gas prices to get there
