I would assume some. We've got a couple for boys teams locally that are getting done Monday and TUesday. The south had a few snow days but a high number of evenings where because of road conditions the district shut down extra curriculars.
In interlocked leagues its not such a big whoop because they don't have regionals. I think I've mentioned in the past my preference for interlocked leagues vs regionals but that is another topic for another day . . .
In terms of the NBIAA site I would say that is as much an updating concern as anything the AD in charge of regional just might not be concerned with the NBIAA getting the info, let alone the schools until later in the week. Or there could be schools that just don't have things posted but the coaches amongst them know whats going. In our case I think everyone knows what the AA girls south and west standings are and who will play whom but last time I checked it wasn't up on the NBIAA site but we know.
