Newbie here.

I've seen plenty of shows at Mohegan in the past, and honestly, there isn't a bad seat in the house. I've been up top along the side of the stage and still gotten some great views. I don't think there is any obstruction in the building.

Also, as far as section 2 seats in the front two rows - I know there were at least some available in the presale. I'm in sec 2, row A.
