Heh, I finished this a few months ago. Pretty realistic.
Lumpy and I would be ok.
She can shoot, I have plenty of ammo and I have the resources available to reload shotgun shells, handgun rounds and several different rifle rounds.
I own 4 compound bows, (well, one is Lumpy's) one crossbow that is deadly out to 55 and 50+ firearms.
I have a 30 day plan, 180 day plan and an extended (2+ years) plan.
I know excellent hunting grounds all over NE and my family owns property in the boonies where game is plentiful and we have excellent relationships with the landowners in the area.
