Organizer: Naperville Jaycees

What to expect: Live music, a carnival, beer, kids activities and a Labor Day parade.

Why to go: UFO! Sorry, ET's not making an appearance. It stands for the United Frisbee Dog Operation, which is just as cool. See dogs flying through the air in this Sunday competition (9:30 a.m.-5 p.m.).

Additional info: Other events include a Big Wheel Race for kids (9-11 a.m. Saturday), a lip-sync contest, and a pie eating contest (11 a.m.-noon Sunday). The Parade will take place on Monday at 10 a.m. in downtown Naperville, preceded by a mile-long run.
