How's this for a statistic:
2 regional/district winners
2 finalist
3 semifinalist and
5 quarterfinals appearances
And almost 4/5 of the field has yet to be seen this season

!!!
Looks like it's going to be a pretty deep regional and a LOT of fun.
Can't wait...
I would not be surprised given the depth of this field to see an upset in the elimination rounds.
My shortlist:
93 525 967 1714 and 2062
Not so dark horses:
141 2052 2169 1806
I will not be surprised to see a lot of successful teams come out of the field though and give some of these teams a run for their money in qualifications and elims.
