I was down there today and watched them install the smaller individual deck boards that run perpendicular to the large beams. They were going at it pretty fast and efficiently. I stood there for under 10 minutes and they lined up at least 1/4 of the length of one row. If that doesn't make much sense, just take my word for it: if they kept up the pace that I saw them installing deck boards at in just 10 minutes, and if they were there the whole day, the deck will have been finished at least 3 of the 8 rows by the end of the day and finished installing the whole deck by the end of the week.
There is still much work to do such as pouring the sidewalk and rigging up the underbelly lights and fish habitat but it looks like this is definitely headed for a June opening.
