Seedling disaster

I left the tomato seedlings out in the greenhouse overnight, and most of them were killed by frost.I wasn't just stupid enough to forget to bring them in; I knew, 100%, that they had to come in.  However, I had some allergic reaction come on in the evening with a rash that spread quickly all over my body with redness and bumps - strange and alarming.  The benadryl I took for that, that I'm not sure I've ever taken before, conked me out like an anesthetic, so that I woke up in the morning howling "the tomatoes!"I ran out and looked and they appeared fine.  They were just frozen in the posture of life, though, and when it warmed up they collapsed, their structural cells exploded by the frost crystals inside them.  I was sick about it all day.Strangely, there was no pattern to the survivors.  Some tomatoes are standing perfectly unscathed, among their fellows looking like steamed spinach.  Same strain, no pattern to where they were on the rack... a mystery.  Either perfectly intact, or destroyed.  No in between.I'm hoping that many or most of them will stage a comeback, like they did after the great chicken decimation last year.  Most of them have most of their stalk intact- still firm and upright, and may regenerate leaves in a few days.  I'm sure their roots didn't freeze.  And we have many smaller seedlings lying in wait in case of just such a disaster, but they will be behind.  It's a setback, any way you look at it.Mystery allergy rash was gone in the morning, thanks to benadryl.  I'd rather have the tomatoes and keep the rash.
