Why A High Tunnel Is Wonderful

I live in north central Pennsylvania and we've had temperatures dipping almost to freezing in the past few days.

And yet, on October 6th, I'm still pulling fresh tomatoes from my (now closed day and night) high tunnel!  

Their texture is not quite as firm as summer tomatoes - but they are still as delicious.  

Maybe even more so because I know how short lived this bounty will be.  Soon it will become a memory only tasted in the homemade spaghetti sauce I've canned.  

And I'll be seeing this...

...until next year's summer harvest.
