So far, Summerfest's attendence is about 15% below last year. That's not a bad thing because being situated on a mile-long strip of lakeshore, there's only so many people that can pack into the place. One reason for the drop off may be re-focusing of musicians and events away from a younger crowd. But another is the competing Country USA festival in Oshkosh one-hour north. If it rains tomorrow, that would hold pack even more people from going to the lakefront. So, if you don't like being surrounded by 90,000 of your friends and you're willing to get wet, tomorrow just might be the day for you to go.

Now, on to the Day 3 highlights.

Headlining the Marcus Amphitheater is Tom Petty. Opening for him his rock/blues pioneer Bo Diddley. They start at 7:30. Ryan Irelan reviewed Petty's The Last DJ, his musical shot at Big Music.
