Yea, the Border Patrol was all over the place. We actually chatted with them at the brake check because we thought that was the exit. They were nice and were asking us if we have ever been out there and to be careful because it can get rough. We also saw another patrol, driving a nice new Jeep Unlimited Rubicon, on the way out at the trail head who helped point us in the right direction to get back on I-8.
I would have liked to hike around the Valley of the Moon just because it looked awesome. Are the 4WD trails difficult back there also? We heard people off in the distance, possibly rock climbing, but couldn't pinpoint where they were. The only other vehicles we saw were a Toyota pickup that was driving way to fast and a Samurai whose driver and family looked like were having a blast.
It probably wasn't very smart to leave the X unattended. :/ Melissa did mention that wasn't a good idea, especially after I told her we were about 1/4 mile from the border.
