Well the wife & I were in knoxville for the week, & we looked at the ZOO web site said to ourselves cool , we went their & paid for the adminission tickets & when we went around the corner to go thru the gates ( you guessed it) there's there sign........ after you pay, after you enter upon property, then you get notified......

SO you have been warned stay away from the ZOO !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
