61,100
Is this closest? Or Price-Is-Right rules, closest without going over? If Price-Is-Right rules, I'll go with 1. Otherwise, I submit the answer of 61,100.
A couple of you have guessed duplicate numbers. Numbers are first come, first served. You can change your guess all you want before 10 am Central time tomorrow morning. Here's a hint: due to construction, the capacity of the stadium is temporarily reduced.
