Ok Phil - According to GH Day rules, if the sun is out and the creature sees its own shadow it will go underground for 6 weeks fearing the conditions aren't right. MS underground for another 6 weeks? Sounds right.
Oh but what a great oportunity to pick-up some more cheap CVI! Surely they can't fall much further than this? (Didn't somebody say that at 20c?)
Phil, what your guess as to how long this will continue?
