Not exactly F class, but I shot my first tactical match at Sac today. We were at 1K when the gusts got so bad it broke off both 2x4s of one of the target frames. On the second relay the winds were tearing the targets off the frames even with 20-30 staples in them. They called the match not long into the second relay due to safety reasons so a target frame would'nt break again and possibly hurt somone in the pitts. What a day!
