Option 5--I have a pistol, 11 rounds of ammo, a backup food supply (beans), and water purification tablets. I ate clover in the last round, so don't need to eat again yet.
It's always a good idea to get food. Having a backup for a backup is just good sense. But, I'm not approaching the RV directly, in case it's a trap. I'm also not going to try to take all the cans. If the person who put these outside is honorable, I will be, too, and not take more than my fair share. I'm assuming it's an honor system here with one can per person, if everything is legit.
If it is a trap, at least only trying to take one can will allow me to get away quickly. Also, I have ammo for my gun now, and make sure I keep a strong hand on it, hidden in by bag, so I can draw and shoot with swiftness if I run into a bad guy or gang here.
Making my group stay behind, hidden in the bushes, I take the responsibility for getting the potential can of food myself. I am the leader here, after all. I can't go risking my people unnecessarily.
Hopefully, this is a good decision, and I will make a new friend for our group, and get some food, too. At the very least, I'll get a can of food if this all goes well.
