Best to think it thru, and sketch it out, before proceeding.@aart, thanks. Greenhouse framing led to Canopy framing, and I found what I was looking for. I also found out that they are $8-10 each for the corners, and over $20 for the four arm pieces. I don't know if we will be able to find pieces that match the angles of the existing run. I do not want to spend $100-200 on pieces, do a bunch of cutting and fitting, and be under the gun to get this done when we have stuff that is already made.
Now I need to talk hubby into my original plan... Maybe just read him the above paragraph?
Oops, forgot about the potential broody,
was in nest last night, tho quiet, and not this morning.
Just found her in the nest and ticking. SMH.
Guess I'll have to set up the breaker crates again,
just put them away!
All of our goldens were terrified of fireworks. Maggie just gets pissed off and runs to the picture window growling and barking. It's going to be a long afternoon/evening. Hope they drink themselves into oblivion early on. 

WTH I look out, and there are strobing blue lights zipping around the backyard. It's the friend's dog with some sort of collar with flashing/strobing blue lights. I chase the dog down my driveway screaming, "I'm tired of this 'stuff' at near midnight." I'll admit I also dropped a few 'F' bombs screaming like a lunatic for a significant period of time. The next day they started putting up a fence in their backyard to keep their dogs and the friend's dog. Problem apparently solved. There's more than one way to skin a cat.
