From the Knoxville Zoo FB page:
Now through July 4th, you can buy one zoo ticket and get another one FREE at all Knoxville area Kroger stores! You can get a great deal now and have the rest of the year to use your tickets. You know it's always a good idea to have a couple extra zoo tickets in the pantry. :)
