I talked to Pete, he's getting the posts from Kencove. Due to freight costs it really only makes sense to get them by the tractor trailer load. I tried to convince Paris Farmers Union to stock them, but that didn't go anywhere.
I didn't know Red Cedar grew down here, I guess I don't see any because most of the land down here was cleared at one point.
edit
Actually it should have been, Eastern Red Cedar grew this far North. It's Northern White Cedar that people typically use for posts up here, the map shows the range down here, but I never see any except for ornamentals until you get up past Pat's areas (North).

Back to the original topic, this fall I built a 6 strand high-tensile sheep fence for someone, not far from Pat, extremely rocky conditions, small fields, a bunch of gates so a ton of bracing. It ended up costing about $3.40/ft with everything but the charger. There was also some labor intensive custom work around the stone walls.
Last Summer I built one for somebody on a field that was a little more coastal, all clay, few rocks but drought like conditions and the clay was like ledge. I ended up having to sharpen posts to bust through without breaking them.. They were only about 20 minutes away. 5-strand HT sheep fence, no charger, that one was only about $1.20/ft.
I have done a terrible job tracking my time on my own fences to figure out what the costs are, but materials are below a dollar/ft. All of these were done with the lesser expensive CCA .40 treated Red Pine posts from TSC.
