As I've said, motivating enough volunteer workers to do heavy labor under the 'time gun' without driving them away is difficult.
Yes, the enjoyment, camaraderie and satisfaction of doing needed trackwork here sounds strong and certainly eases the work effort, per the small amount of spike banging, tie lugging and creosote smoke-hazed trimming I've done.
How to get consistent, unpaid,"full days work" through the whole weekend?
A tough one.
