Other cold tolerant plants to consider, parsnips, spinach, carrots, winter squash is cutting it close...
Parsnips, spinach and carrots will get sweeter with the cold. Spinach can actually tolerate snow on the leaves. Napa is also better with the cold. It's considered more as a winter crop.

If you have near 80F at the end of September, you'll be able to get Delicata, acorn/queen, kabocha, squash. One of the best summer squash is Trombocino lot of meat and very little "core" with the seeds.

And don't forget to plant plants that will attract bees!! You need bees!!

Whew!! reading how you are hauling all the garden stuff makes me tired!!
