So on Facebook I saw that this Friday June 17th is Flip Flop Day at Tropical Smoothie. If you are wearing flip flops, and they do check, you get a free 24 oz Jetty Punch smoothie from the hours of 2 PM- 7 PM
I also found something free for Dad's at a neat place called FLIPnOUT Xtreme on their page you can click to get an offer for Dad's to get free entry on Sunday June 19th.
Here is their Facebook link https://www.facebook.com/flipnoutxtreme/
Another mention is On_Camera_Audiences.com still has some free tickets for live tapings of American Ninja Warriors this weekend.
