Well, on my calibreated monitor the post IS blown out.
The easiest way to avoid such things - Zoom alot closer to the post, so it takes large part of the zoomed image, the press AE-Lock button. This will fix the exposure needed for normal brightness of the post. Then zoome out, compose the shot. The surroundings will be dark, alot darker, then you'll want them. That's ok. Take the shot.
After that use Photoshop to control levels of the photo (CTRL+L) and Shadow/Highlight option (Image->Adjustments->Shadow/Highlight) to get what you want from the dark image you've taken.
Hope that helped
