But without Bob Johnston, the "Junglemobile" program wouldn't be what it is today. Bob was its very first driver, and has since traveled to over 70 events in Colorado, Nebraska and Wyoming.

"Bob just has an amazing passion for serving children, and that's evident when you watch him interact with kids as part of this program," Erin Baum, prevention and education coordinator for Children's Hospital Colorado, said.

The "Junglemoble" was initiated in 2000 through the Kiwanis Pediatric Trauma Institute at Children's Hospital Colorado. It provides injury-prevention education to children, mainly in rural communities. Johnston, a long-time Kiwanis club member, drives the vehicle to a location, where it is unloaded and various hands-on stations are assembled.

"I think [his] passion has really inspired other Kiwanians throughout metro Denver to become involved with this program," Baum said. "This program is entirely staffed by volunteers who drive the Junglemobile out to community events."

Baum says in 2011 alone, Johnston traveled to events which served over 700 children.

"[The] last 17 years I've been in Kiwanis - kids are our thrust," Johnston said. "And that's what we like to emphasize in our service - things we do for kids. Somebody will say, 'We've got this project.' I say, 'Oh, that sounds like fun,' and I sign up. So I just keep doing all these things because it's just what keeps me happy and keeps me young."

The Junglemobile program is just one of many ways Johnston has served children in the community. He volunteered with the YMCA in Denver for over 30 years, and also tutors elementary students in Jefferson County Public Schools.

And, in an interesting juxtaposition to his cowboy attire, Johnston has a passion for Native American culture. He owns his own teepee, and volunteers his time at a YMCA camp on reservation in South Dakota. He says he once cut and stripped 100 pine trees to help make teepees for the camp. He's also given Native American lessons at an outdoor lab with Jefferson County students.

Johnston says volunteering comes natural to him. His father was a YMCA camp director, and he became involved with the organization at a young age. He says the rewards he's gotten from his volunteer experiences far outweigh the investment in time and money.

"I think that one of the best things young people can do to improve their lives, to learn about themselves and to learn about the world is to volunteer," Johnston said. "Do something - and you can do it, you just don't know it. You haven't done it yet. Long ago I adopted the philosophy of my childhood hero - Li'l Abner, the comic character. And he said, 'Any fool can do that, I can do it.' Jump right in and go do it. You'll be amazed what you can do."

Johnston turns 80 in December, and despite a recent bout with pneumonia that put him on oxygen, he is remarkably healthy.

"As long as I can get up and get out of the door, why I'm going to go do what I can," he said.
