Glad to hear your team is going to join the CFOA series. It is a great series to play. The owner, Larry Motes and his staff are great. They will answer any questions you may have during the day. Great group.
Like the guy above me said, get your ID online. Then you pick it up at the first event you attend. During the morning of the event, you will hear someone on a loud speaker announcing where to pick up your ID or get one if you didn't do it online.
Familiarize yourself with thecfoa.com
web site for the rules and the deadline to register and pay for your team. The Sunday at midnight before the event is the deadline for payment.
Now that you have your ID's pre-purchased and your team registered and paid, you think about game day.
The field layouts and game schedules can be found here or on thecfoa.com about 3 days before the event. Find it and print it out.
For the event:
Don't forget to pack your tent and plenty of water or Gatordade during the hot months.
You can bring your tent to the field the evening before or the morning of the event. There will be an area to put your tent, tables, and or chairs. There will be a separate area for the vendors.
Chrono and PAC time your gun before the first game at the field. Again, read the rules of the series.
There will usually be 4 fields set up with 2 separate set ups. You will most likely play at least 1 game on each field. However, you only have to learn 2 field set ups.
You will play 6 games and depending on the amount of teams, a certain amount of teams will advance to semis, quarters, etc...
You may have anywhere from 15 minutes between games to 45 minutes. The fields run ahead of the posted schedule you found online before the event. You can also get a schedule at the event.
Again, this is a great series. It is run top-notch. The reffing is run very consistent with zero tolerance.
Bring your parents and friends. They will enjoy it too. It's a great environment.
