Well aluminum and zinc don't have the same color, they polish out and hide some of the difference but you can see it, it's all just for fun though. I still have some polishing to do unless I get bored.

Funny thing is I prefer the look of the zinc.

Yeah, zinc has been used for 250 years to galvanize steel and later other metals. It can be deposited by electroplating or, originally, a melted zinc bath.

Lol, BowtieGuy. I was wondering where the garden was.
I've just had one of those Chinook's fly over my house. Do you still ride around in them frequently Alaskan?

Wow, that's not a lot of foliage. I wonder why they even bothered. They look like conifers, but it's hard to tell for sure at that distance.

It's a bush, I don't know where the dividing line is between what a bush or a tree is, but I'm calling it a scrubby bush.

Scrubby bush. Ok, if enough people call it that, that is what it will become. Semiotics for you.

Yeah, I guess it depends on what its potential is. I have two huge holly trees on either side of my outside stairway. They are at least three stories tall, but when they are small, not very impressive.
