Best way to west side of Mt. Adams, WA from I5 southbound

This weekend it probably doesn't matter how you try to get that far south from B'ham because it's going to be very congested. That said, I would get to Randle on US12 any way you can and then head south to Takhlakh Lake...I can't remember the FS road numbers, but I assume that Paulj's road info is accurate. IF it's not raining you'll have an awesome view of that beautiful mountain.
