You are most welcome! I highly recommend that you attend a basketball practice.
On practice days, I always enter the LNC by walking down the long ramp at the far south end of the LNC. Practice may be on the practice court or on the main court. Just follow the sound of the bouncing basketballs and you cannot miss the practice location.
If practice is on the practice court, just make a right turn (eastward) as the ramp enters the arena, and walk right in and sit in one of the folding chairs set up against the walls next to the court.
If practice is on the main floor, continue walking down the ramp inside the LNC towards the main floor and sit anywhere inside the main arena. If you sit on the first row, then you will likely be greeted sometime during practice by one or more of the players or coaches, especially if you get there early and stay until the end of practice.
If you wish to confirm the practice times, call the OU basketball office during regular business hours at 405-325-4732.
