I was out at the range today and someone ran out in front of me and flagged me down. They told me that people were getting flat tires. She showed me a bent up nail that she had picked up. She had hundreds of them. She said she thought she got them all. But then I noticed one right in front of my truck...then another... and another...and another. I must have picked up 75 or a 100 myself. I drove in at a walking pace and warned everyone I saw. It is the range out in East Orchard Mesa. Be careful! This is what they look like. Someone went to a lot of trouble. It must have taken hours to put hundreds of them in a vise and bend them one at a time. They have vise marks on them.
