I'm a new tennis fan and I'd like to start going to see some live tennis at tournaments. I'm in the Chicago area. I'm already looking to do Cincinnati some day (probably 2012), and would love to go to the US Open sometime in the near future. For the time being, however, I've been checking out the schedule for the Challenger tour. There is one tournament played in the northern suburbs in Winnetka starting this month, and another played downstate very close to where I go to school during termtime. Are these enjoyable events to attend? Would you recommend them? Should I go to earlier rounds, or maybe just the final rounds? Thanks.
