Mike, Thanks. I can see your point. How much of a problem do you think that water sitting on top of the bracket will be?
I admit that I was more concerned with being able to raise the end of the post up off the ground which can be done easily and any water will drain out of those slots in the side.
I wll be using pressure treated timber, brown, not the awfull green, and also intended soaking the ends in cuprinol (spirit based) for a few days as well.
