I have found a few soft spots along the Skagit. Never really got to stuck.
I am wondering if any of our Alaskan members have stories of people getting stuck in the sand along the coast line up there. I remember seeing signs along Turnagain Arm warning people to stay off the mud flats below the high tide mark and hearing storys of people getting stuck in the mud with a Bore Tide coming in. I guess some did not survived. Scary stuff.
