Email me when you get into town. You might be a bit early for St Joe, but the St. Maries could have flow in it. Clark Fork always runs, but it's a longer drive. There's almost always something to surf on the Spokane, but some flows are better than others.
If you've got a car with you, and if you'd like to get on something in the 3+/4- range, you could drive down towards Moscow and run the Potlatch Canyon with us. Lolo's only another hour past there if you're up for something a little bit tougher and more remote... one of the best runs around.
