You “heard” full auto firing at 0240? Why did your night watch/LP not report it to you? Sorry if I sound harsh, but it seems you were not practicing bugging out so much as you were playing “hiding in the woods”. That just might be because to me bugging out is so much more than just getting out of the house to the alternate location.
