Reading this post, seems like a more likely outcome. Snowflake Survival duo would probably be mobbed, robbed and beaten for their weapons and pack contents.
Second thoughts...
Perhaps a better urban GHB would contain items like:
Small, concealable gun and extra ammo
Medium size concealable knife
Small flashlight
Dirty worn/torn/loose-fitting clothes
Worn-out looking comfortable shoes
Small sealed containers of dirt, grease, beer, foul smelling liquid (your urine?) for rubbing onto clothing and self
City map
Heavy duty ziplok freezer bag large enough to contain watch, ring, wallet, anything personal that someone might think they want. Hide it well and hope you live to retrieve someday.
Try to look homeless and beaten down by the world when anyone is observing you. Head down, mumble, shuffle, no eye contact.
Crazy?? Genius??
Probably the only realistic shot at getting out.
My solution is to damn near never be ITP. That place is a freaking war zone even on the best days.
On the rare case that I see any of the ATL news, it is damn near 100% shootings and carjackings.
