Interesting site. Loads slowly (but then I'm at 33.6).
I'm sure it's just compression from the telephoto lense (loss of depth perception from picture taken from distance) but it looks as if, in the opening picture that they have two lines of fire - one in front of the other. I will assume they are doing it safely and it's just a firing line that weaves back and forth and it just looks like two lines of fire.
Good to have more groups supporting the sport! Thanks DD for posting this.
