For people who have been to champs, your response is “Yeah, that’s champs. There’s a lot of teams. It’s big”
For people who have never been to champs before, you’ve captured the huge-ness of the event pretty well here. 6 competitions and 400 teams under one roof takes up a ton of space. Even more when it was 8 competitions and 600 teams in St. Louis. It’s been fun watching my rookie students for the past two years be amazed by the difference in scale between our 45 team DCMP and the 400 team CMP.
And keep in mind, this was just inside the main hall. In the same building there’s also 2 FTC divisions, an FLL competition and JrFLL exhibition, innovation fair, reception area, volunteer lounge, and a bunch of other places all full with FIRST people. You can’t really imagine the scale of it until you see it in person.
P.S. - not to turn this into a Houston vs Detroit argument, but I’ve been to both now and the layout in Detroit is a lot easier to navigate. The fields and pits are in two parallel lines so that each division’s field is right next to their pit. So even though the room is just as big, you only need to walk the whole length to enter/exit not each time you want to go between the pits and fields.
