Spindletop-Gladys City Boomtown Museum, on the Lamar University campus, will transform into a 23-obstacle mud run on June 21, from 10:00 a.m. to 4:00 p.m., as part of the museum’s second annual Great Outdoors Day.

“Many people realize that families need to unplug and enjoy the benefits of outdoor play,” said museum director Mark Osborne. “At Gladys City, we feel we have a unique opportunity to help promote having fun outdoors.”

The highlight of the event will be the Mini-Mudder Romp, a mud run for children ages 6-12 that will test their physical and mental endurance as they climb, roll, jump and crawl their way through the course.

Adults can attempt the course at the end of the day in a “No Child” heat, and a special Tiny Mudder area will provide water and mud play for children five and younger.

Other activities include several outdoor games, a disc golf course sponsored by the Golden Triangle Disc Golf Club, and special guests from Village Creek State Park, the Big Thicket National Preserve, Neches River Adventures, Big Thicket Outfitters, Sons of Confederate Veterans, Big Thicket Outlaws, Beaumont Camera Club, and Mathnasium of Port Arthur.

Plus, the Lucas Gusher Re-enactment will take place at Noon and 4:00 p.m.

Registration is required for the Mini-Mudder with a $20 fee per child and $10 for adults running the No Child heat. Registrations will be accepted until 11:00 a.m. on June 21. Additional details may be found on the museum’s web site – www.spindletop.org, or by calling 409-880-1750.

Admission for museum visitors and spectators is free all day. Spindletop-Gladys City Boomtown Museum is located at 5550 Jimmy Simmons Blvd. (corner of Hwy. 69 & Jimmy Simmons Blvd.) in Beaumont. Free parking is available.
