Craig's Story
In the middle of Craig's pain, he stomped the snake to death. The 47-year-old is currently recovering. He feels well enough to do television interviews. The
Standard-Examiner of Utah reports the man was at Wal-Mart May 11 when he reached down for what ended up being a 20-inch long brown rattlesnake. Craig said he was at the store looking for
mulch to grow medical marijuana."
Maybe that's why he thought a rattlesnake was a "stick".
