Yup, CL is the first step in any low budget engineering quest. It's too bad so many folks are scrapping wire because I used to find big runs of romex in remodels and teardowns. Not anymore. Good luck with your hunt for wire. In one of the picks it looks like your power and phone wires overhead.....too bad there's not a box to tap into closer to the gate.
I see my buddy PJ's is lurking this thread. I'm just the idiot recon, he's the engineer. If we get in too deep a yogurt the Wiz will get us out
