Many fall happenings this weekend. Some open both days.

Fauquier County Parks and Recreation is hosting Touch-A-truck 2016 on Saturday, Sept. 17, from 1 to 4 p.m. at the Warrenton Community Center, 431 E. Shirley Avenue.

Children’s Science Center Lab at Fair Oaks Mall will celebrate its first birthday on Sunday, July 24, from 11 a.m. to 6 p.m. with a day full of free or $1 festivities and unveiling of two big, new “gifts."

Graduation time should be a positive experience, one that a graduate will never forget. As your teen navigates this important life change there is much to do and talk about—but the most important conversation should come from you, the parent. Explain to your child that during graduation night and at other celebrations, safety is crucial in the planning process, and that alcohol, drugs, and cigarettes are not necessary for a fun time!

Choose from among train show, parade, hike, concert, dinner, bowling, basketball tournament, farmers market, historic sites, suffrage play and more!

The annual event from Aug. 14 to 22 includes livestock and produce exhibits, home arts and crafts entries, thrill rides, live music, food, nightly entertainment, baby contest, rodeo, demolition derbies and much more. Through the years it has been a fun and educational attraction and this year will be no exception at the 66th annual fair, at the Fairgrounds, a mile north of Manassas on Va. Route 234.

So many choices (20), so little time. Walking tours, historic sites open, charity run, ballet, play, air show, Arts Alive!, new fire & police exhibit, free book event, car show, farmers' markets and more!

Get outdoors for gardening workshops, bike tour, foot races, farmers market and more or inside with a concert, charity event or historic house tour this weekend in the Prince William County / Manassas area.
