Sharing a fence, neighborhood gardening.
We live in the suburbs with regulation 6' fences. Our next door neighbor is an avid and fantastic back yard gardener.
She plants gourd plants every year (for 32 years). Her plants creep over our common fence and we harvest her crop together.
Lol, this year, both of us had a surprise when we pulled back the vines and and found a nearly 4' gourd. See the yard stick.
Oh, I can't help it, Sometimes the gourd is bigger on the other side of the fence. Lol.
