Break out the T-shirts and flip-flops. Dust off the lawn chairs and coolers. Summer officially arrives Tuesday, and there is no better place to savor it than Prince George's County. To welcome the season, we've compiled a list of some of the many activities planned for residents and their families and friends. The activities, as varied as street festivals, fairs and Fourth of July and Labor Day observances, are as varied as the county itself. For example, if you're into music, you may want to drop in on an outdoor jazz or rock concert. If you prefer movies, try watching one outside at Allen Pond Park in Bowie or Granville Gude Park in Laurel. Whatever your preference, get out of the house and enjoy.

Fireworks will burst forth on the Fourth in Laurel, as seen in this 2004 photo, and at least five other locations in the county, which also will offer parades and music. Mathew Whelan, left, and Anthony Harvey, with Maureen Whelan, were in their red-white-and-blue best for last year's Fourth of July parade in Laurel. Basketball star Allen Iverson, left, warms up for his annual Celebrity Softball Classic, scheduled this year for July 16, to benefit disadvantaged children in urban neighborhoods. Above, a slightly rougher brand of athleticism is required for the annual Bill Pickett Invitational Rodeo, a touring black rodeo set for Sept. 24-25.
