As if keeping 445 acres of parkland gleaming with verdant radiance wasn't enough, the young professionals who support Hermann Park Conservancy's efforts set out to do just the same on the stage of Miller Outdoor Theatre at Thursday's soirée "Glow in the Park."

For this social, Urban Green members forwent business attire and painted the town neon with luminescent hot pinks, oranges, yellows and blues, opting for bright ensembles and accessories that flickered from a dark, black backdrop. Think incandescent hoop earrings, twinkling tiaras, flashing cartoonish sunglasses, powered snowflakes and, of course, glow sticks.

Chairs Caroline Bean, Cynthia and Chad Mabry and Megan McGraw, with the assistance of event plannerGraham Gemoets of Butter & Company, encouraged an assemblage of 300 to pore over a silent auction offering gift certificates for dinners, art performances and a stylish Mary Nichols clutch.

Though it was the opportunity for one lucky winner to walk away with a 30-minute thrill ride in an experimental RV-4 aircraft, which promised loops, rolls, Cuban Eight maneuvers and all sorts of daredevil acrobatics, that had bidders' competitive juices going strong.

Saint Arnold Brewing Company's Christmas Ale was a popular choice among the party goers, alongside the Mar-glow-rita and the Glow-tini of Dripping Springs Vodka. A hearty spread of hors d'oeuvres from Last Concert Cafe, Pappasito's, Adair Kitchen, Raising Cane's and sweets by Relish Fine Foods satisfied the thirsty throng, some of whom grooved to fly tunes courtesy of DJ MAV.

Among the good-doing illuminati were Andrea and Rob Fineman, Tom Broughton, Nic Phillips, Divya and Chris Brown, Kevin Dewhurst, Katie and Brian LaRue, Kevin Bauman, Marrisa and Michael Alexander, Stacy and John Andell, Brad Carter, Melissa Robey, Wesley Wilder, Mike Castele, Mandy Lewis, Daniela and Erich Canseco, Sarah Livesey and Gwen Bradford.
