Only have a chance to do a fast look over during lunch, but I saw one big thing- KI tablets. They are only useful as a pre-exposure treatment, and it takes several days to have the full effect. And you can only take them for a relatively short period of time, if you took them every day you'd be in bad shape in a month of so. Long story short, unless you KNOW when the nuke is going to go off, they aren't worth squat other than psychologically. And if you know, I know people who would like to talk to you before hand.

QuikClot is good if used properly, but it isn't idiot proof. Something like Bleed-X is a better choice, as there is not exothermal reaction. Using QuickClot inappropriately is a good way to add 1st and possibly even 2nd degree burns to the wound, while Bleed-X and the shrimp stuff doesn't have that risk. Go back throught the past week of postings, and you'll see threads about both products.

If you have that many people, you are probably better off with a tent.

Skip the splenda- calories=survival. Use sugar. You might want to put the soap in another bag, or your tea will taste like soap.

In the nice to have, a charcoal or resin based water filter or a reverse osmosis rig.

I didn't see rain gear, or work gloves.
