Yes colonial era but not RW. This looks like it would be fun, they have an encampment plus a battle. If you are not engaged in a shoot this weekend I will probably see you out there on Saturday. I will likely be riding my bike.

Went to this yesterday. Of course wore my Appleseed shirt and got lots of interest from the reenactors. In fact the guy who organized this event and who is in charge of a re-enactor company asked if they could come to our shoots and demo some of their weapons, clothes etc. "gee, let me think on that for a mllisecond, abso-friggen-lutely!" I got his contact info and passed out business cards.
They have a battle at 3 pm, they drew a couple hundred people yesterday so I am thinking of going back out with a pile of tri-folds today to pass out to the crowd. The battle was pretty cool actually.
