There is a thread on mtbr in the trailbuilding forum about how to motivate individuals to participate in constructing mountain bike trails. One of the ideas mentioned is that some corporate employees are required to do community service and have joined the trailbuilding ranks. I don't know if they are mountain bikers as well but we can always use the help for our ongoing project at Salisbury.
Since I am not a member of the corporate world I don't know much about this topic. I'd be curious if any of you have heard of the corporate community service thing.
Here's the thread. Some good replies from all over.Even mentions beer!
