First Frost?! This Early?!?

Why should I be surprised?
After a slow start and incredibly hot stretches, why should I be surprised by anything like an early frost?  It was 90 degrees just two days ago!
So this evening, I'll be pulling out all the plastic and bedsheets that I can find to cover all that I can.  My beans are little babies.  My peppers are teeny tiny.  My tomato plants are loaded with gorgeous, GREEN tomatoes.  The cucumber vines are still pumping out fruit.  The basil is still gorgeous.
Really, we should be getting another three weeks of growing time here in Zone 4.  But, as my sister says, "You get what you get and you don't throw a fit."
But check the weather daily.  Be prepared to throw some tarps over things.  Go to the farmer's market and buy up what you can.
My peppers may never make it to red, but I can probably buy a whole crate of them for $5 in the next three weeks.  I'll roast the red ones and chop my green ones.  All will be frozen for good meals this winter.
