You can't walk three feet without running into a small child toting a basketball-sized tennis ball with autographs scrawled in sharpie on it.

These balls are Wilson tennis balls, but more the size of a baskeball. And yes, they bounce quite high in the air. In case you were curious, of course.

Kids stake out the entrance to the Presidential Suites area, which is nestled behind the practice courts closest to Arthur Ashe hoping for their favorite tennis player to sign their ball. It's pretty adorable to watch.

What's not adorable is the price. These balls retail for $40 bux, which is more than I spend on gas every two weeks. Though its hard to keep them in stock at the various places to buy Open memorabilia. When asked if he sells a bunch of giant tennis balls, a retailer chuckled at me and answered "yes."
