Very impressive Bill ,stunning yard. I go through your area every year in spring and didn't realize zone 7 went up that far inland. Maybe if you're very close to the Seekonk leading to the bay it helps with moderating the temps. In any case you can bet I'll be checking out the cables. It might not be as cost efficient here in zone 6..... 10 degress is huge, but would be an aid to season extension in case of an emergency(like if I ever get an edible flower
). Thanks for the pics and cable link .....which is where I'm heading next!
