Treasures found in our yard

Hubby was grilling tonight and so hubby as usual had the pups out with him in the yard. As Hubby is working on making us our fabulous meal the pups start to bark........at the ground!
Hubby did a quick investigation and discovered a crawdad or crayfish on the lawn! In the ten years we have lived here we have never encountered such a creature!
Yes, we did have some rain today and yes we do live somewhat close to the river but not that close!
Funny the creatures you can find in your own backyard!
