The next day I road the trail and camped at a campground west of Kellog near a town that started with an "E"
That would be Enaville.
The next day I rode over Thompson Pass and camped in a nice campground on the western edge of the town of Thompson Falls that had an all you can eat buffet ( I tend to remember these things)
Did you ride to Thompson Pass/Falls from Wallace via Burke? How was that? Paved? Looks like mostly forest service roads. If I was to do the ride between the trail and Missoula again, I might try that option.
Yes, it extends about 20 more miles to Mullen, one of the strangest towns I've ever seen. I'll leave it at that so as not to influence others' impressions.
The trail get somewhat steeper east of Wallace--one of the coolest towns I've ever seen.
It's only 7 1/2 miles from Wallace to Mullan, but second the steepness of the trail section between the two (but it's not mountain steep, maybe 3% grade, tops), strangeness of Mullan, and coolness of Wallace. It was a shame we only had a half-day to spend in Wallace. Next time I'd take at least one break day there, if not two.
Overall, I think incorporating the Trail of the Coeur d'Alenes is a good idea, difficulties of getting from the east end to Missoula notwithstanding. It is definitely scenic, west half more so than the east. And the east half has Wallace. Plus, we saw a moose!
