We're supposed to get upper 40s. Meh. I have these two giant green tomatoes that are, like, a pound each, and I'd like them to ripen one of these days...
You know, if you have a frost coming for sure, and you pull the whole tomato plants up and hang 'em upside-down with the dirty roots and all in the cellar or laundry room or whatever, the green tomatoes on them will get properly ripe just fine. You can easily get another month's worth of tomatoes like that, on account of them ripening slower in a bit of a chill, but it's kinda nice to have a few fresh tomatoes per week until a month post-frost.
