It's a Chukka

Not something you get to see everyday.... We happened upon a polo match and pulled in to watch. Each player has 4 horses (no wonder it's an expensive sport) because they play each "chukka" which is 10-15 min. on one horse, have a quick break, switch up and play the next chukka. I told Erin about it on the phone and called it "quarters" of each match, and she said, "oh Mom they're called chukkas". I had heard the term from the announcer but figured she wouldn't know it. How wrong I am. She's very well read :)
