Roy,
That was the worst flooding the N-SSA has had during a Nationals Skirmish.
They bought the land in 1963 and hold two Nationals a year. One in the Spring and one in the Fall.
Many other Regional shoots are held there during the year and some of them have experienced floods that can be as bad.
This is just the first time it had been this bad for a Nationals.
Perhaps, the important thing is that may of the shooters stayed and after the water went down by Friday afternoon the shoot continued for Saturday and Sunday
My best,
Blair
