If they get the 1st practice in but qualifying is rained out, then the pole goes to the fastest in 1st practice. If both 1st practice and qualifying are rained out then pole goes to the leader in owner points (I think) which is the #99 - Carl Edwards.
That would be too easy to figure out. I think we would be better off just cancelling the pole picks when rain cancels 1st practice and/or qualifying. Just my thoughts.
