Ahh yeah. Did that in a canoe a while back, like when the town flow was above 3000 cfs. Took about 3 hours. Nice placid float. As you leave durango to the north, on 550, you'll come to 32nd st (City Market corner). Take a right, north, and as soon as you cross the bridge, turn left, and the take out is obvious. To find the put in, continue north out of town on 550 for several miles....at least 8...you'll see a sign on the left for Trimble hot springs, and then instead of turning left to the hot springs, turn right onto the paved road (Trimble? I think) and after a mile or two there's a put in near a bridge.
