Behind the seat....
The key is to have a 1993 rust bucket F 150......Thieves see that and just think, "Nah.....Nothing worth stealing in there..." Plus my EDC bag is an old diaper bag with an old baby bottle filled with water on the side....Even if someone sees it in there they are going to assume there is nothing of value inside....I have found the easiest portrayal for me is a middle aged redneck without a pot to **** in.......
I am pretty good at doing that persona......
I have always been a grey man when it comes to prepping....
At the rate I am beating up my 04 GMC I will be there soon enough.
