Re: Advice for yellow Lot Tailgating...
To get as close to the bubble as you can, parking on the concrete and going all the way down towards the bubble would be the way to go. But as mentioned, the earlier you get there the better.
The closest corner of the grass area is probably about 35 or so yards from the gate that leads out of the yellow lot, across the street to the bubble. And depending on where you are on the grass...you can get there early and be on the 1st row, but if they park you on the north end of the row, you'll be much further from the gate as opposed to being on the second or even third row on the south end.
I do not know how it works on the concrete side. All I do know is that as of the last tailgate, when entering, if you want grass you need to be in the 2 left lanes and if you want concrete you need to be in the 2 right lanes. That, of course, is subject to change.
