When in looking for these of blue balls connected to a string. The guy at the front didn't know exactly what they were and said to go back to the Outdoor Sports. I had to wait a few minutes but when the guy came to the counter he knew exactly what they were. You help me find them online and order more. They go to a tailgating game but my dogs found them in the schoolyard and they love playing with them. Thank you so much Dicks Sporting Goods in Countryside Mall.
