Metal and fish

[Roger L.]

I try to do it when I meet vets or active duty, thanks for your service JCO. I'd shake your hand too but my arms are a little short.

Couldn't agree more, Roger L. Thank you, JCO, for your service to our country. Airports are a good place to find Veterans in their service duds. I approach with my hand extended and thank them. While waiting to board, over the intercom, I heard "We have extra room in first class, if anyone would like to upgrade." I went to the desk and asked "Why don't you give those empty seats to our service people?" She said that after the boarding is done, they start at the front of the plane and ask if they would like a free upgrade. They continue until all the first class seats are full. Now that's first class for those first class service people, IMO.
As for the topic, I remember seeing a lot of stainless at a Salmon hatchery in Jueano Alaska, but they have an endless supply of salt water they pump from the ocean. it flows through the hatching and raising ponds/tanks and back to the ocean. My guess would be that because the hatchery is constantly changing the water, the concentration of metals would be extremely low, to none. Why stainless and not PVC? aquaally

From what I am told, stainless has the least amount of transfer of particles of all metals and it doesn't rust if maintained.
