depends how harsh a frost. - usually they will survive the first one, but then the plant will die and you will have a load of soggy leavs with pumpkins sitting amongst them!
infact sometimes this is the only way to find them all!
we had a frost the other day and picked our pumpkins and squashes. they are not completely ripe, but last year I ripened one from dark green to orange in a cool sunny window
these are mine, now sititng in front of the french doors
