It seems that my team's kick-off plans change from year to year.
This year, the county school board is much more "involved" than they were last year, which is never bad. They have highly encouraged that we attend kick-off at a county location along with other teams from the county/region. (We have like 6 teams in our county alone

)
So we have accepted and we will be meeting there to watch the kick-off. We will be sending representatives down to the Georgia Tech Kick-Off to pick up the kit of parts.
Usually after the kick-off, we give things a little time to simmer and we go to lunch. This gives people a chance to work the rust off some ideas that they immediately thought of, and we wait for the reps that went to the official kick-off.
After lunch break, we usually take about an hour to go over the game, make sure everyone is clear on how it's played and some of the ins and outs of more complex rules.
And then we dive into brainstorming. We generally spend about 2-3 meetings (each is about 3 hours long) thinking of ideas, and from there we generally break into prototyping, building chassis, gearboxes, etc.
