There is no way he should have been able to avoid good trackers. He had help or they weren't looking as hard as they say.
you would get on his track and then all of a sudden you had 100's of people comeing into the area searching for him and that would alert him to tracker's in the area ..
alot of people never knew this part the people at the lower level where allways beening riden by the upper level to produce him in a so many hour's instead of letting them work the area and search and do a low tech of following the tracks out ..
there was allways the upper level personal flooding the area with personal and then he would vanish into the track's that they left ..
a few tracker's teams left over haveing to work like that with the FBI and it got to a point towards the end where they where alot of infighting inside the two groups over how the people where trying to find him workedand it show in there performace in the field ..
the upper level personal never understand the basic fact that it take's time to run down a track to a point to figure out where it went or if it was him or not because they allways want you to produce in a couple of hour's or less if the track was his or not ..
plus there was this little know fact that some of the local's out in the woods where he had been seen makeing tracks to **** off the upper level FBI personal over how they where treated by them dureing the first couple of years beening up in the area ..
there was a couple of time's he just vanished into thin air on a couple of hunt's for him and i do belive that someone picked him up and moved him to a safe spot and helping with food supplies and other items to keep on the move ..
