what’s with all the backpacks?
These sites are called “layups” in the coyote business. The illegals hole up at these sites to wait for their rides farther into the U.S. They change from hiking clothes into street clothes and then dump their belongings so they can cram as many illegals as possible into the waiting vehicles.
Backpacks are dumped as clothes are used up- change clothes throw away dirties and when backpack is empty then throw it away. Backpacks found near roads are a different deal- drugs are packed in backpacks and then when drugs are loaded into vehicle backpacks are thrown away.
