Practice Field(s) at Championships in Atlanta?

[Ken Streeter]

Thanks for the answers to the question about practice fields at the Championship -- it's good to know that a practice field will be available.

How were the practice fields managed? Was it simply "first come, first served" on the field for one team at a time? Was more than one team able to use a single field at once? Was there a sign-up sheet with teams signing up for times in advance? With around 80 teams in a division, it seems like there might be a lot of contention for practice field usage, especially on Thursday. Any more information would be greatly appreciated!

Thanks!
