You can find out who you are playing with in any competition by going to FIRSTinspires.org Under the Community tab select Team and Event search. Select Event filter. Unselect the programs you do not want to find events for. Select the current season. Select the country you will be competing in as well as the state. This will pull up all of the Events in that state. Simply select the Event you are competing at and a list of all Teams that will be attending will pull up.
Knowing who you are competing against prior to the Event will help you prepare your scouting list.
