This is what's causing the button-drop in the newsletter form and I'm not sure it's necessary. Of course, without it, the wrapper goes back to 1000px and the layout looks too spread out, so I assume that's why you narrowed it in the first place. But I think we could move some other things around and make it work better at the regular width so this page would be consistent with other sandstone pages.

I'd shift the calendar image a bit to the right in the header so it balances better and doesn't leave that big void in the middle, then center the "items" list with some padding on each side of its container. That's pretty much all it needs.
