I plan to do my new cathedral ceiling in knotty pine:

This is the best price I've seen. I'm going for a lodge/tavern type look, the walls are done in red cedar, I'm building a bar later as well. Indirect LED tube lighting pointed up at the ceiling, with hidden fixtures. I figured pine would lighten the room up a bit. The stuff I'm getting is unfinished, I wonder should I leave it unfinished or do some sort of clear poly?
