Just going to echo some problems that we might encounter when trying to organize a shift of New York to the district model.
1) Hosting district events in NYC would be hard.
On the other thread about NY districts, there was a lot of talk about how NYC has really large schools, citing Townsend Harris, Stuyvesant, and Brooklyn Tech as examples. As a student at Stuyvesant, I can testify that the population numbers are deceiving. Even though our school has over 3500 students, the building is 10 stories tall. Unlike large schools outside the city, our school is not really a suitable venue for a robotics competition. I have also talked to members of team 2601 from Townsend Harris who have said about the same. Brooklyn Tech is probably the largest school building in the city and might be able to host a district event but that would probably not be enough.
2) New York is the go-to regional for international teams
Due to a myriad of reasons, NYC regional has become a regional with a high international attendance. It's part of what makes the regional so special. While many people say that international teams could just get automatically invited to DCMP, this places them at a severe disadvantage to teams that have gotten practice at their district events. It would be an unpleasant experience for teams that are often already at a resource disadvantage.
3) DCMP would probably be in NYC.
This is a more controversial point, but the NYC regional is a large publicity, helping NYCFIRST pick up sponsors, as well as hold robot demonstrations for sponsors. NYC regional has lots of competition tours as well as special robot demos for the sponsors. Having a big show event in the city is pretty important. This issue is easier to work around, because it is possible to hold the district champs in NYC, however, staying in NYC can be really expensive, and a lot of the teams that are pushing to shift to districts, want DCMP to be held upstate. Obviously this isn't make or break, but it does take away from one of the primary incentives for the district model: saving money.
I don't mean to be a wet blanket but a lot of people on this thread seem to have their head in the clouds. These problems need to be addressed before NYC can shift to districts.
