You are going too far too fast for a first time group of strangers and you will get a smaller turn out.
It is an Indiana forum so by definition a spot in Indiana is closer to more people. Choose a spot that allows easy camping, more will turn out. Avoid State parks, a lot of these guys will have guns no matter what rules you lay down.
The location I gave you allows you to do all the things you listed. An easy base camp for Friday arrivals and those who can only come one day/one night on Saturday. some guys will drop by only for the day on Saturday etc.... Multiple camp sights so grab as many as you need, the place will be empty. Trails that run right by the location OR you can drive south to to other locations, park and head out for a day or two of primitive in HNF. Don't turn it into a big dump your mags shoot or let it go that way.
Doing the above, you will end up splitting the group after day one, but if you only do what you are saying, you will reduce turnout by 75% anyway. I would never show up for what you propose with a group of strangers for many, many reasons. Guns or no guns, alcohol or no alcohol, hiking or not, primitive camping or not.
Last thing I want to do is show up to an event with alcohol, trigger packs and Federal CI's. It happens
There are reasons why I have not publicly hosted another event since 2003, but I have friendships and many get togethers that formed from the ones I did host a decade ago.
If you build in some meet and greet time, groups of like minded and skilled people will form up sub-groups and friendships from the first event. There will be more after that but they will be private, you will never seem on a public thread. No need for that. If you already know 30 who would possibly show up, you have no reason to do this anyway.
If you go commando in winter with strangers, you may just end up hauling someones ass out of the woods to the ER and the fun is over. All it takes is one .223 round and a 1lb propane canister. Alcohol and an axe. Drugs and fire. Combine them all and it gets even bigger faster.
Just some thoughts for you.
Well said.. I agree, keep it in Indiana, smaller group(s), might try one and see what shakes out. Booze is a personal choice to me but if I am somewhere and someone gets stupid, I leave before it gets to be a problem. The CI comment is more real than most imagine.. To me a group of 5 or 6 would be better than a group of say 20.
Just my pennies..
