If it is a single log, dont count the boards till the log is opened up.
If it is white oak you may want to do quarter saw.
Keep the logs a little over 8 ft long, maybe 9. This will allow for waste on the ends.
When felling, have the hinge plunged out so that the holding wood is only on the outside, this will keep you from loosing wood from the hinge splintering.
seal the ends with exterior paint as soon as possible to reduce splitting. I've heard some people are bagging them, no idea how well that works.
