Least I forget...to be fair to my son's bride, I'm also the happy and proud father-in-law of a young woman, and veteran soldier herself, who likewise recently returned from Afghanistan after an earlier deployment to Iraq.
Yes, I come from an American family that has proudly served for over a century in the service of our country, starting back when Pershing marched into Mexico in 1916 with my maternal grandfather among the 6,000 American troops trying to catch Pancho Villa and his bandit army following their attack on Columbus, New Mexico during their Mexican Revolution. He later died from the Mustard Gas he was exposed to in France during WW1. The sons were all too young for WW2 but several, to include my paternal grandfather, my father, and several uncles participated in the Korean War. During the Vietnam War, there were at least 6 family members, to include myself, my grandfather, my father, two uncles and a brother-in-law to serve there. All but one returned, my brother-in-law, an Intruder pilot shot down by a SAM missile over North Vietnam in 1968 during the latter days of Operation Rolling Thunder.
I can imagine that there were others, earlier in our history, but those who could recall such matters never spoke of it in my presence, so I leave it as an unknown. Besides, if they did they were probably fighters for the Confederacy as my family's roots are in the south - Texas.
Jet sleds/boats destroy redds in the spawning grounds with their turbulent jet wash, scouring the bottom and further burying some of the eggs while ejecting the rest into the stream flow to be eaten. To protect fish, these boats must be restricted from the spawning grounds.
