I'm at home sick, have been for days, and taking care of sick kids too. What is the exact question we are trying to answer here? I can't read through all this stuff.
Sorry to hear about the sick family, been there done that.
Matt, the original question was...Can someone make a biological case for a later season or lower limit?
