I have been studying maps and searching forums, trying to see if anyone has ridden the Idaho Centennial Trail north from Thompson Pass, in between Murray, ID, and Thompson Falls, MT (Trail #7). I have been trying to talk the wife into attempting it from the pass to Idaho Point and back, about a 70-80 mile ride on (supposed) single track. I am looking to find someone who has done this ride first to see if it is realistic. We are both very capable riders, but if we will be spending half our day dragging our bikes over impossible rock faces while teetering on the edge of a 2000' drop-off, I might think twice. 5 years ago, maybe. But kids drastically change what your concept of "dangerous" is. Thanks for your input!
