Went camping this weekend at padre...So much fun.. However, this time my kiddo walk back to the dunes behind out tent and starts screaming " Rattlesnake!! DAD!!! Rattlesnake!!!!!"... sure enough right at the edge of the dunes in the sand.. was about a 3 ft western diamondback. he had stepped within one foot of it and it started rattling at him and slowely crawled away.... scary!
