Milt,
Here's some info on Spotted Bear CG:
http://www.fs.usda.gov/recarea/flath...66838&actid=70
I've only driven the west side of Hungry Horse Res, never driven the East Side road so I can't give you any info on the ride, but you'll have about 55 miles of gravel; make sure you have a full tank of gas and a good jack (since you're from B.C., you already know about being in bear country). Miles and miles of wade access to the river. Have fun, catch a bunch.
Regards,
Scott
