I'm familiar with Union Bag and Weyerhaeuser, but not the others you mentioned. GP, Plum Creek, Rayonier, and International Paper are the others I'm familiar with in my neck of the woods. Rayonier used to have a bunch of land around here.Union Bag, St Regis, Great Southern, Georgia Kraft, Weyerhaeuser, and another one or two I can`t remember.
