USA, Texas, Rio Grande gravels: What did Mike Tyson really do with that ear after he bit it off? I don’t think he really gave it back to Evander like he supposedly did in that commercial. My theory is he grew tired of carrying it around with him and tossed it in the Rio Grande while visiting distant relatives in Laredo, TX. From there it made its way all the way down to the La Joya area where I found it. Or, it is just a beautifully polished, uniquely shaped agate. I will let you decide. 2.1oz.
