Here are some recollections from the old pit days that might be of some help to you first timers.
1. The place will be hot ( assuming that not much has been done to the heating/cooling system).
2. Those of you on the first row will be able to 'talk to the opponents' quite easily.
3. One toilet each for men and women.
4. Concessions ( if they have them ) probably will be in one corner of the pit.
5. It will be noisy. Sound really carries.
6. You will hate your hard seats about 10 minutes into the game.
7. Lighting should be poor compared to the SuperPit.
8. Speaker system will be hard to hear.
9. Come to the old pit in a surly mood....it is not uncommon to stand and boo the opponents during their warmups.
10. When you leave, you will say 'man, that was fun, though primitive.'
