...As long as we're moving trees...Red Oak

Let me follow the threads on moving apple trees with my own thread on moving Red Oak. I need to replace an American Elm that we cut down this fall. I want to put in a Red Oak because it is relatively slow growing and retains it's leaves well into the fall/winter.

I want to go as big as I can, however, I've got a restriction of about 48" (diameter) on the hole that it can go in. Now I realize a root ball that big is a monster to deal with. For practical handling reasons I'm sure I'll need to go with a much smaller ball.

Anybody here have experience with moving or transplanting this tree? either from wild stock or nursery stock?

Appreciate any suggetions...or references on retail nurserymen who could advise.
