I rode from Sedro to Concrete it was absolutely beautiful. My only complaints are that I didn’t know that the trail broke in 2 areas and was lacking directions to find it. Thankfully there were some nice horseback riders in Hamilton who pointed the way. Then again at Baker lake a couple told us to cross the highway bridge. At the end though, near & finishing to Concrete the trail was sandy for a good 3 miles beautiful but used extra energy pedaling through. I will be doing the trail again and want to go & return on it next time 
