Picking up two guys on the Colorado river where it boarders Mexico is a little sketchy. I timed their journey well, and arrived at about the same time they did. There were Boarder Patrol in the area, and they became pretty interested when I meet up with two guys coming out of the river. Luckily I had their packs so the BP didn't have much gear of theirs to search, and after checking our shoe tread, we were free to hang out around the dam.
This was the end of the easy part of the trip. The logistics of getting into Mexico and down to the Sea of Cortez would be hard, because there is no water in the river bed after Morelos Dam. The Colorado is a dry river bed from the dam for about 75 miles down to the Sea of Cortez. That means it is either hike or try and navigate the maze of dangerous irrigation canals. The canals can't be counted on to have water flowing in them, so at any time you can run out of water. When I wasn't at work I tried to help them figure out some of their logistics, before sending them on their way.
Here is the first video of their trip.
