Nothing, not a thing... my backyard has no fence and is about 8ft deep.... oh wait, my wife is growing zucchini next to our a/c unit... hahaha. I live in a 55+ community and no fences, tiny yards cost me $12 to have taken care of so $24a month.. barely get the gas for that. both disabled so this low maintenance was the way to go. Mongo misses his big fenced yard to chase lizards all day... but man I hated cutting that monster yard mower in one hand, cane in the other.. cuz we poor white folk.. lol
cherish dem yards... I miss mine a lot
