Trade 2 Cubs Tickets

I have 2 tickets the the Cubs/Rockies game on Thursday July 31st. The game is at 1:20PM. They are bleachers tickets. I am looking to exchange for either a weekend or weeknight game. They were a gift for my girlfriend, and she started a new job and can't make it. One of the night games the 28th, 29th, or 30th would be awesome. If interested, call Steve at 224-425-3861. Thanks and Go Cubs!
