I've never been to the stadium in Harrison NJ it's mostly for soccer/football however it's very easy to get to from New York City via the PATH light rail train and it's the only show in the NYC area so no surprise it's selling fast.Should be getting Hellfest, a 2nd NJ show, and Latin american shows pretty soon
I got mine in the presale but it was not easy every time I selected something a popup message would say they were no longer available.
