I see a large amount of NWI events or gatherings posted in the forums. I have not seen much in regard to central IN around Indy. I was curious if there were groups that gathered on a somewhat regular basis or if the area just needed someone to organize it and that is why there isn't much.
Check out Indiana Self Defense or East side prepper store in a search. I don't recall the specifics, but they discuss all sorts of things from what I have read in that thread.
