You'll find activity on Butler-Freeport Community Trail on any day of the year and at any time of day. This Saturday marks the beginning of another chapter in the popular trail's history.

From 10 a.m. and 1 p.m., Butler-Freeport Trail Council will hold a groundbreaking ceremony at Franklin Field on Herman Road for the final length of unfinished trail into Butler.

Butler's mayor, Summit Township supervisors and others will dig a shovelful of dirt to symbolize work on the final four-mile project that connects Butler's Father Marinaro Park with the southern terminus in Laneville.

Volunteers already have begun clearing the path of brush and trees in anticipation of heavier construction later on.

"We have a good core of volunteers," said Butler-Freeport Trail Council president Chris Ziegler. "The same five show up every time with their chainsaws and pruners."

The half dozen steady workers, plus a few more, have been working on the northernmost part of the trail, which is usable but in rough condition. Work on this final four miles should be completed in about a year, depending on funding.

Historians will be on hand Saturday to discuss the trail, which served as a passenger and freight rail route from 1871 through 1978.

Saturday's half-mile Community Walk to Butler is free. There will be free hot dogs and drinks and a free raffle for both a kid's and an adult's bike. However, there will be a small fee to participate in the Chinese auction for several gift baskets.

The completion of Butler-Freeport Community Trail will mean the culmination of decades of work. The trail officially opened as a 2.7-mile route in October 1992. Over the years, the trail overcame legal challenges and funding constraints to become today's popular recreation venue.

Drink up. Be sure to take in more fluids now that the weather is warm. Water is the drink of choice for exercise sessions of less than one hour, but any noncaffeinated, non-alcohol drink will do — just watch the calories.• <B>Day 1:</B> Walk 5 minutes.
