Should do I buy tickets in advance for the 2018 finals Nov 8-11th or can I buy at the gate?

For better seating I would buy in advance

Cheaper to buy now than at door prices

If you want good seats I would buy them now . Otherwise you will be down at the finish line or who knows where.

Either or , i dont like reserved , i like to watch from a different spot each round

Advance to choose seats.

If you're gonna sit in General Admission, you can buy at the track. If you want Reserved, get them now.

Thanks for the info
