I was going to use Mammmoth as one of my safety air****ts today, but
found out it was closed for resurfacing! The NOTAM states
MMH 05/005 MMH AD CLSD EXC HEL ON PRKG APRON TIL 0809150700
So those soaring near Mammoth air****t (at the base of the Sierra
Nevada Mountains in California for the rest of the group) be advised.
