while out course designing for our new 'Enduro' I discovered nearly every small holding that backs up to the jungle, has a small bike track that has/is used for bamboo cutting or some other felling. These tracks can be anything from 1-6 kms in length, have recorded dozens of them around Sai Yok Yai area, I tried to link some together, generally it doesn't work because if it had been that easy to continue along these tracks, the Thais' would have already done it, So the most fun I can have with this hobby is to just set a waypoint and just try to link them. The failure rate is a about 99% and hours of hacking about in the jungle being eaten by moises. Probably better let some one else do it and just read about it, sat at home on your PC. Just remember any difficult track through woodland took a lot of time to develop, if you don't use it, we will lost it back to mother nature.Thats why I love the locals who made and use these tracks, so please respect them !
