WWPR is right. We paddled Gore on Saturday last weekend and it was on shore. We personally stashed it a bit further from the river then it was when we found it. Someone must have pushed it back in. That ain't cool for a number of reasons but the first two being that it may get stuck in a good line somewhere, not to mention what it does as far as getting Search and Rescue fired up for nothing...
Whoever own this boat, get it out of the canyon. Unless the guy/gal broke some bones, there is no reason to trash the place by leaving a boat in the canyon just cuz you swam.
