Got Frost -- But no Pumpkin

First time I've seen frost since early May in southwest Colorado (had snow then too).  It was 31 when I first checked earlier upon getting up after sunrise so, it may have been colder before then.  Toes are still cold so, will not plan to fish until possibly midday from the beach or maybe the causeway -- the beach should be warmer, I think, since the skies are absolutely clear (for the time being).  Chance of rain is expected for tomorrow.
