Hmm...the list is okay, but you forgot the midwest. From what I see, the following states have a notable number of Jazzers (included are number of people who would fall into that category):
- California (Southwest)
- Kentucky (Southeast)
- Maryland (Northeast)
- Minnesota (Midwest)
- New Jersey (Northeast)
- New York (Northeast)
- Ohio (Midwest)
- Tennessee (Southeast)
- Texas (South)
- Washington (Northwest)
- Wisconsin (Midwest)

The problem I mostly see is that there are a lot of Jazzers coming from California, and less so from New Jersey, but still a lot. There is not much else out there other than California with many Jazzers, except for Washington; Oregon and Arizona have very few, and the Rocky Mountain states have nearly none. Here are states with a lesser number, but still some:
- Alabama (Southeast)
- Arizona (Southwest)
- Delaware (Northeast)
- Florida (Southeast)
- Georgia (Southeast)
- Idaho (Northwest)
- Illinois (Midwest)
- Kansas (Midwest)
- Louisiana (South)
- Maine (Northeast)
- Massachusetts (Northeast)
- Michigan (Midwest)
- Nebraska (Midwest)
- New Hampshire (Northeast)
- New Mexico (Southwest)
- North Carolina (East)
- Pennsylvania (Northeast)
- Virginia (East)

Which leaves the following states with very few:
- Alaska (Completely unconnected)
- Arkansas (Midwest)
- Colorado (Rocky Mountains)
- Connecticut (Northeast)
- Hawaii (Completely unconnected)
- Indiana (Midwest)
- Iowa (Midwest)
- Mississippi (South)
- Missouri (Midwest)
- Montana (Rocky Mountains)
- Nevada (Rocky Mountains)
- North Carolina (East)
- North Dakota (North)
- Oklahoma (South)
- Rhode Island (Northeast)
- South Carolina (East)
- Utah (Rocky Mountains)
- Vermont (Northeast)
- West Virginia (East)

Basically, the thing is that most of the people in the JJ2 community live east of the Mississippi, but there are a lot of people out west in California, and less notably Washington and the southwest. It is likely that most of the players in the midwest would go to the eastern meeting if it was somewhere like New Jersey, while those in Texas might go either way. Jazz 2 players around Vancouver would definitely go to the west one, while those around Toronto, probably east. There are more Jazz 2 players overall in the east and, all things considered, the west meeting in the Rocky Mountains areas to accomidate the midwesterners is not necessarily a great idea. The Rocky Mountains are not exactly highly populated. The other question is where to meet for the westerners? San Francisco, California might end up being a good midpoint. The easterners might meet somewhere like New York City.

EDIT: Having North and South would be sort of odd...if northwesterners had to go to the northeast it would be more driving because the U.S. is longer than it is tall. Besides, the midpoint for northerners would be *shudder* North Dakota or so, and southerners would be *shudder* around Texas...
