Well....where did these 26 chromosome guys come from? From the HIPS

Next winter (is that this weekend? brrr), I'm going to wade thru the
pedigrees of all of this latter bunch and see if they seem to fall in
groups & then try to get more of them to torture here. So far, I have
at least one 50 - ROSY WINGS (now y'all can see another reason I picked
that one to experiment with), and if I follow Dave Holm's suggestion, I
may wind up with a LOT of ROSY WINGS :) .
This is the wrong time of year to be doing all this heavy thinking!

temps right above freezing 3 nights in a row (some scattered frost) - at
this rate, a hard freeze tonight shouldn't do too much damage.
