In Hillsboro. I did set them in concrete and sloped the concrete to
drain the water away.
The whole key is to keep the base of the post clear and use enough
gravel for drainage.
My neighbor put a fence up the same time as me and used Cedar, his
fence is still their, but he is noticing some rot just now. I wouldn't
worry about rot using PT lumber at all. Just install them right.

I've just pulled out about 6 posts that I put in almost 25 years ago. Set
them 2' deep, no concrete and a standard 1x6 'dog ear' 6' tall fence. I was
pleasantly surprised to see that there was NO rot on the posts at all. I'd
never intended to leave the fence up that long once the kids grew, but never
got around to removing it. We're in the centeral Ohio USA area, maybe not
generally as rainy as Portland, but it was very damp where the fence was
located - often got a couple inches of standing water after a good rain due
to poor drainage.

Of course 25 yrs ago we used the 'good old' arsnic preserved wood, not the
stuff they havce today.

My drainage is very good, but in fall/winter/spring it is not unusual to go
for weeks and weeks without a non-rainy day. Anyone know how good the new
posts are? Maybe I need some creosote :)
