I thought I remember them saying they could bring a gun, but it counted as one item along with each bullet as another. Also, I thought somebody had a bow.
They did show someone with a bow, but it was to tease ahead to future episodes. I'm not sure if he made it. I don't think anyone brought one in.
If you look at the bios on the History Channel website you can see everyone's 10 items. I looked at them all and don't recall a bow on anyone's list.
A lot of people chose the same items. That makes me think the producers gave them a list of 15-20 items and they had to pick 10 from that list.
