This is one of my favorite events of the year. Not only can you get the canon smoke during the 'battles', but you can get some great portraits of the reenactors in period costumes.
There is also a very good one, at El Dorado Park, in Long Beach, around Memorial Day, but with parking and the entrance fee, you will spend about $40. The Huntington Beach event is FREE!
This is not a formal meetup, so there is no RSVP fee -- the event is on both Saturday and Sunday.
I plan to be there, on Sunday, about 9AM, to shoot the encampment. The first battle is at 11AM, on Sunday.
I've done this a couple of times and some of my images are here:
For portraits, I suggest something in the[masked]mm range.
PLEASE: Do not RSVP 'no', if you are not going. I will send my cell number to anyone who RSVPs 'yes', in case you want to meet up on Sunday.
