115 was a great section on the Mezzanine level. Don't purchase these tickets anticipating seats on the lower level, the 100s at the Prudential Center are more like club seats.
There are only 6 rows in this section so it is a great family section with maybe 8-10 seats per row. Also right next to the concourse which will have your bathrooms and concessions. Beautiful arena, just wish the Nets were staying.
