Yesterday morning a dejected group of river runners was sitting at Lee's Ferry with their boats fully rigged. They were saying that they weren't going to get to launch. That morning 9 Sheriff cars had descended on their camp at the putin with drug-sniffing dogs, and gone through every drybag. Five of the men were found to have substantial amounts (over 5 ounces) of marijuana. The Park was not involved in the bust. I do not know how the Sheriff was alerted. As far as I know the Patriot Act still contains a section making one a terrorist if caught in the possession of one ounce or more.
The outfitter that had brought the group to the put-in had to come back up to Lee's Ferry, de-rig and take them back again.
