I have found the mileage on the small map they hand out at the rangers station to be 'off' a fair bit. I have a full size map of the whole trail I purchased several years ago. But, I've been told they are planning on a new map since the trail has changed some since Katrina. I plan on being in the Wilderness area this week some as I'm off and wish to do some exploring down that way. I'll tote my machete and axe.
