1) Drinking and firarms, Rule #1 is don't be stupid, I am not going to stop anyone from having a drink but if they are getting obnoxiously drunk or they are out of hand and they are sober they will be asked to leave or removed, You can do some shooting and later around the campfire have drink, don't be stupid do no harm etc.. I am fully libertarian, as long as you don't harm anyone else there isn't going to be a problem.
2)I will have a bow drill set and after the walk I took it looks like there is materials on site to make your own to take home with you, I will also bring some spindles of yucca for you to try as well as it isn't native to the area. everyone should have some cordage with them.
3)As for what to bring I suggest packing like you would for a day hike, if you only have a full pack then use it. To prevent environmental impact I suggest a tent but if you want to build your own shelter to sleep in there is plenty of woods available if the weather is wet you could bring a tarp and sleep under it, the goal is to impart knowledge with some practical skills. there is a mix of hardwoods and balsam/pine forest take a look at the first post it will give you some coordinates to look at the area. if you want I can also look into bringing some hay bales to use as debris instead of leaves which would have fewer bugs and dirt mixed in the down side is there is a cost associated with the hay. I will most likely be under a tarp because it is always in my back pack and sleep on the ground in my jacket and a solar blanket.
As for additional skills if someone can come up with some approx 5" diameter log sections maybe 3" deep I can teach you how to make a bowl. I can also teach you how to make your own rope. I'll look in my garage and see if I have any cat tails but there are other plants we can use and I am certain we can find them out there
FYI The shelter itself normally takes a couple of hours to build even as a group once you get proficient it normally takes under an hour
