Mark your calendars because Caldwell Zoo in Tyler is offering up two free admission days on September 30 and October 1, 2017.

I gave Caldwell Zoo a call this morning and they confirmed that they will be doing 'Phone Book Recycle Days' on September 30 and October 1. That means for every phone book you bring (outdated or not), you get one free ticket for admission that day. So if you have four of them laying around, you could bring your family of four... and so on.

The Go To Mommy originally posted the good news on their Facebook page and guest relations confirmed it's true. So start collecting those phone books and ask your friends if they have any old ones laying around - it could mean a free fun day at your local zoo.
