I guess it depends how serious you are about the game and what kind of exposure you want to experience.
Here's my two cents on some of the areas mentioned.
Minnesota, one of the strongest areas period with the likes of Tony Spredeman, Dave Gummeson, Phil Goatee, Steve Mohs, among others. But from what I hear from Brandon Moreland who has moved back here to Dallas, there is only one tourney a week.
Lincoln Nebraska is a good honorable mention. Deliza Baumback has just moved here from that area and she said they have some good things going on. They have no major ranked players in the area but they are a close knit group that care about the game. What they lack in skill and experience they make up in passion for the game.
South Louisiana, great place, my home state. They also have a great scene going with a good promoter. They also possess a guy who has one of the most wicked push kicks ever. And the best food going. Jobs on the other hand, don't know.
Texas, my current state. The Austin area, cool place, a college town, Good job opps.. From national polls I have seen, one of the cities to move to in the US. Lower ranked players but again, guys that love the game.
Houston area, solid area. Lot's of skill and experience here with a good promoter. Players like Tracy McMillen, Chad Hansen, Scott King, and John Smith are in this area.
And as Ben said, the Dallas area is just crazy. Every night but Sunday there is a tourney. Sat. night there are three to choose from. What I like about this area is the diversity of players here with great skill to learn from. Ex.
Mike Archer, great brush series and good defensive five also.
David Radack, tic tac passer, also a great goalie.
Denis Ory, he is the one that Billy Pappas got the lane wall series from, if speed kills, he would be an assassin.
Frank Espinosa, wicked and unique brush series that is pure hell to block.
Brandon Moreland, top ranked player period.
Warren Vanlandingham, good five and wicked rollover.
We also have alot of good up and comers making waves
We have one the largest if not the largest state tourney and this year, Worlds is coming back home to Dallas. Always nice when you don't have to travel to the largest paid tourney in the world. Being centrally located is also nice when traveling to other tourneys.
Not saying we are the best, but for sure we are the most active scene in the country. And like the foos, the job scene is pretty diversified.
Just my two.....errr, three cents.
