Expanding Foam for Setting Fence Posts

Guy who built my deck and fence used the foam on the fence posts.   I don't know what the cost difference is, but it certainly seems like it would be easier.  I had to screw the post where the gate closes to the garage.  The post where the gate is hinged isn't sturdy at all.  I'm not a fan.

That makes perfect sense to me. 60 to 80 lbs of concrete at the bottom of a gate post is a heck of a counter balance.

I came to a stop sign and a skanky tweaker chick in a tube top climbed out of the brush and propositioned me.  She looked like she didn't have any teeth so I counted that as a plus.
