Come ON, Tomatoes!!!

It is now the middle of September and I can still count on one hand the number of tomatoes I've been able to harvest from my tomato plants. I know I got them in late (being nine months pregnant at tomato-planting time was not conducive to gardening), but there have been nice, juicy, large, GREEN tomatoes on my plants for about a month now, and they show no sign of changing color! I think it's just been too cold for them to ripen.

This week looks like our last week of warm weather, and I was hoping the tomatoes would realize this and hurry up and ripen already. Next week it looks like we may have a frost! I'm beginning to think tomatoes aren't as smart as I've previously given them credit for...
