I hate it when people won't take a hit. For our tactial battles we use something called the graf system, its very easy and we have judges who watch the battle. If anyone started yelling about someone else not taking a hit that person would lose points for there side.
Here is a link to a whole bunch of reenacting units

Just look around and I'm sure you'll find one in new jersey, I know for a fact there are reenacting units in that area. I just can't remember which units.
Also today about an hour ago I had a reporter for the local newspaper interview for a story about my reenacting and they ended up taking a big picture of me with all my uniform and gear around me, while I had my helmet and k98. I can't wait for it to be the paper. It should be out by next week and hopefully I'll scan it and be able to post it here.
