I am running this thread in several boards, just seeing what the diferent ideas are.

There is a thread on the local truck board talking about trail alterations
http://www.alaska4x4network.com/showthread.php?t=18511
They bring up some interesting points of view about maintaining the historical nature of a trail, moving rocks out of trails (or back into trails actually), building bypasses around parts of trails and when or who should be on the trails.
These questions may be only able to be settled with a bottle around a campfire but what do you think?
Should trails be improved at all?
Do bypasses around wet/rocky/steep sections of trail ruin the trail?
