Oh man, before they closed K.I. Sawyer these babies would fly around here at tree-top level.
You would here a rumbling from off in the distance. We'd all start to look around saying "Where is it?", when all of a sudden SCRREEEEEEEEEEWOOOOOOOOOSH it would pass right over or nearby our heads. The sound, size and fury was an awesome sight to behold. In the summer time this would sometimes happen several times a day.
I live within the confines of the Big Bear training area. Unfortunately, now all we seem to get around are high fighters. And they are only visible on very rare occasions.
