[SCCC] Acceptable RTTY frequency range on 10M

[Loren Hunt]

I'm planning on participating in this weekends WAE RTTY contest and specifically on 10M since it is now open. 
I can't remember ever doing a RTTY contest on 10M. For RTTY in general I have been operating between 28.080 and 28.100. 
Question:
What is the acceptable frequency range for 10M RTTY during the contest?
What areas should be avoided?
