Three Central Texas men were honored with the Texas Department of Public Safety’s Director’s Award in a Tuesday morning ceremony for their heroism in saving the victims of a serious twocar accident.
The accident occurred on March 25 when a vehicle lost control while traveling on rainsoaked State Highway 6 near Baylor Camp Road. It ran into an oncoming vehicle, leaving the occupants trapped inside as both vehicles burst into flames.
Bonge was the first on the scene and heard children screaming. He broke through a back window and pulled Mallory Smith, 10, and her sister, Megan Smith,9, from the wreckage.
The girls’ mother, Beckie Smith, was not with them at the time of the wreck, as they were traveling with their baby sitter, Lisa Bowbin.
Beckie Smith still remembers the sickening feeling she had upon receiving the call informing her of the wreck and the despair as she drove to the scene.
Bozeman and Clemmons arrived shortly after Bonge and helped rescue the other victims and attempted to put out the fires.
“I was nervous,” Bozeman said. “I don’t feel like I’m a hero. I was just doing what anyone should do in that situation. I hope someone would do the same for me.”
Everyone at the accident made it out alive, with the victims suffering from nonlifethreatening injuries. Mallory Smith broke both femurs(股骨), and Megan had neck and back injuries. Bowbin is still recovering from a broken pelvis(骨盆), ankle and foot.
The rescuers also were taken to the hospital and treated for cuts and smoke breathing, Bonge said.
In addition, Bozeman got to meet accident victim Anthony Russo in the hospital after the accident, where Russo presented him with a glass frame inscribed with “Thank you”, Bozeman said. Those involved in that fateful encounter on Highway 6 credited God blessing for bringing them together.
“Whatever the circumstances, Tuesday’s ceremony provided a time to be grateful for those who put their lives on the line for the lives of complete strangers,” Beckie Smith said, “We’re calling it The Miracle on Highway 6.”

New findings from Queen’s University biologists show that in the plant world, bigger isn’t necessarily better.
“Until now most of the thinking has suggested that to be a good competitor in the forest, you have to be a big plant,” says Queen’s Biology professor Lonnie Aarssen. “But our research shows it’s virtually the other way around.”
Previous studies showed that larger plant species monopolize(垄断) sunlight, water and other resources, limiting the number of smaller plant species that can exist around them. But the research has proved that this is not generally the case in natural vegetation.
In the Queen’s project, PhD student Laura Keating targeted the largest “host plants” of 16 woody plant species growing in the Okanogan Valley, British Columbia. The research team calculated the number and variety of plants that neighbored each large host plant. They then randomly selected plots without host plants and calculated the plant species there as well. The research showed that the massive trees have no effect on the number of species with which they coexist.
Smaller plants have many advantages over their overbearing neighbors, Professor Aarssen notes. Larger species generate physical space niches under their shelters where smaller species grow well. Smaller plants are much more effective than large trees at using available resources. They also produce seeds at a much younger age and higher rate than their bigger counterparts, and settle down much more quickly—thus competing with the newly-born plants of larger species.
