Alright heres something I thought of and this may sound stupid, but lets say you decide to bug in or out. If your in the woods or at home wouldn't it be nice to have some way to tell who's kinda on the up and up. May sound silly but if me and mine our moving through the woods lets say or were at our chosen place and we run into a man and his people both sides may be a little edgy given the lack of food, water, whatever. So it might give a little peice of mind if you could tell he was a like minded individual. What I'm trying to say is in war they have challenges like if I run into someone and I say thunder he better say lightning or I start shooting. Likewise it would be nice to have a way to identify such non family and friends that may be friendlies. Like if I'm dug in and one of you guys shows up hiking through with your family I may not want you to move in with me but we could be civil and share a smoke, a meal, and trade info. So how would we go about knowing that the other person is friendly. Or do you guys think you should just dig in and forget everyone else? Just wondering. I've run into a lot of good people on here and between us all we have alot of resources something bad happens it seems we could have our own hpa underground railroad going if you know what I mean. JMO.
