This cache is the very southwest of the continental USA! Of course we had to make our cache hunting complicated by getting to the 3 mile round trip hike right at sundown. It was gorgeous being on the beach at that time, but by the time we got to the Mexico USA wall, it was pitch black! A border patrol came up to us, was very nice, but said to stay away from the wall and stick together since that had some climbers who might be hiding out after going of the wall today! Wow! So we got the cache and booked it back to the car. What a neat and exciting experience!
