I have the numbers for the various District Rangers. I always try put together a rough trip plan and then call the Ranger(s) to walk through it with him/her/them for any and all kinds of issues along my intended path. I'm not quite there yet, as I am still trying to decide what that route will be.
I'm just looking for someone that lives up that way to lend me there wisdom, based on their knowledge of the area and maybe some first hand observations on snow melt and stream levels. A guy can always hit up the sno-tels, etc. But, no one knows better than someone that lives in the area and spends year after year out in it. If you can find "that guy", you can even get updates on the conditions, as the trip draws nearer. Sometimes, you even get lucky and get to hear a great story that they encountered while out in the area you are heading to. Bonus.
