What Lyons said. They've reached max height on the structure itself. Right now they're mostly working on internals, trying to get it sealed up for work this winter. Facade work is progressing, but I haven't had any time to go over there to get pics for a while, and for that I apologize.
As far as the Arena, they've got a few more roof trusses up, but not as many as I expected as quickly as the first few went up. They have the upper ironwork ring finished (upon which the roof trusses are resting), and quite a bit of the peripheral stuff (those protrusions that stick out from the side of the thing) but any pics I take right now won't look a lot different than what you've seen lately.
If I can find time I'll try to run by both places again this weekend. We'll see - no promises.
