"It's all about skills training and service to the community," he said. "Scouting took you outside of your box. It gave me perspective on what I could do to help others and be a better member of society."

MacLeod also cited the way those experiences increased his self-confidence as an important part of his development.

"We did a lot of hiking while I was there," he said. "I finished the C&O Triathlon, and I never thought that I could do anything remotely that hard."

The active nature of Scouting has enabled Gray to maintain his enthusiasm for the organization.

He points to the high-adventure component, which includes experiences such as the annual C&O Triathlon, as proof that Scouting is more than camping trips, projects, and merit badges.

The triathlon begins in Cumberland and ends in the Georgetown neighborhood of Washington, D.C. Scouts hike 11 miles, then canoe down the Potomac River for 50 miles before finishing the arduous trip with a 120-mile bike ride.

"Usually, it's the first trip for our 11-12-year old age group," Gray said.

"That's the first high adventure," he said. "But we've also sent groups to Isle Royal in Michigan, the northern tier of Minnesota, and the Alaskan wilderness. Those are the kinds of trips that keep kids involved in Scouting."

Sunday, the state park will be an opportunity for young and old troop members to talk about their experiences.

For most of its existence, the Catonsville Presbyterian Church has been the home of Troop 306. The connection started when the Rev. John Nesbitt, the church's pastor in 1911, went to Mount Washington to hear talk about the organization by Ernest Thompson Seton, a naturalist, author and wildlife artist who was the first Chief Scout on the founding board of directors of the Boy Scouts of America.

Troop 1, which eventually became Troop 306, was officially chartered in June 1911 and began meeting at Catonsville Presbyterian.

"We've made it to 100 years because they've always been there for us," said Gray of the church's strong support of the troop.

While Catonsville Presbyterian has benefited the troop 306, the Scouts have also worked to strengthen the bond with the church. Members of the troop perform many seasonal services at the church, including February's Scout Sunday, cleaning the church grounds, building composting bins and helping with the set up for special events at the church on Frederick Road.

The troop's service also extends to the greater Catonsville community. Eagle Scout projects have made a visible difference in the area. Those projects include: raising garden beds to allow patients in wheelchairs to plant flowers at a local nursing home; constructing benches and outdoor sitting areas at nursing homes and churches; organizing toy drives for the Catonsville Children's Home; collecting books and constructing book shelves for the Ronald McDonald House; building and clearing trails and working on erosion control projects at the state park.

Sunday's celebration at the park will open with Gray leading the Pledge of Allegiance followed by an invocation by the Rev. Kovacs. After presentations to the church and troop will come the most interesting part of the official ceremony. The troop's newest Scouts paired with older Scouts will provide history lessons from their times.

Gray said his committee had three primary goals for the reunion:

• Present binders that detail the troop's history to Catonsville Presbyterian Church

• Coordinate Scouts of all ages to help find other older Scouts

• Build bonds so the troop will have a 200th anniversary

Following the cutting of the anniversary cake, attendees will have the opportunity to view scouting memorabilia. The afternoon will conclude with a recital of the Scout Oath and Scout Law.
