Sorry I dont know any links offhand..most likely Stratics has something. How it works is that you decode a map and it stays decoded for about 30 days (therefore the location is static for that time). After 30 days if the map has not been completed it reverts to tattered and has to be decoded again with a new location. The locations can be anywhere even sometimes in towns. If you have any vet rewards get yourself a Davies locker. You can store up to 500 maps. It gives you partial coordinates too which sometimes help.
Aye I remember you and Theresa..Welcome back!! I am sure you will get into the swing of things before long
