I have multiple BOL's, some including islands... I shouldn't give out ALL my BOL's... sort of defeats the purpose but I live on a Long Lake.. (pun) and there are islands out there that are fairly secluded.How many others do you think might be thinking the same thing about that island? I'm not trying to say it's a bad idea, just make sure you're looking at all angles good and bad. Islands can be good if you can feasibly support yourself and whatever you have with you. They can also be death traps because you can be waited out, much like an opposing force would camp outside a castle's walls and just wait for the people to slowly starve.
IMO the type of bugout depends on the type of situation you are trying to get away from.I understand where your coming from, can't take any chances. What would be other good BOL locations
