Hoping for tickets to the pricey but oh-so-fun-filled Red Sox Picnic in the Park this Sunday? As part of my baseball season long partnership with Tickets for Charity (TFC), you have an opportunity to win tickets by playing a good ol’ game of I Spy.

The low-down from my friends at TFC:

The event is so special, the team at TFC decided to put together a fun contest to give away the tickets. It’s called “I Spy with my Fenway Eye,” and here’s the catch: entrants will need to bring their Fenway-insider A-game to name 10 people, places and things we found around the park last week.

The game is tough—but worth it for a chance to win the Picnic tickets, where players will be signing autographs and auctioning off amazing prizes. And of course, it’s all to support the great work of the Red Sox Foundation. Details about the Picnic event can be found here.

Try your hand at this fun game with a great prize here. But hurry! This contest ends on Thursday, July 21 and the winner will be notified via email 9 a.m. on Friday morning so they can make their weekend plans. So give it a try and see if you can snag tickets to this popular event!
