Whats this line of flowers near not on any roads or anything?

I'm new and just turned on flowers for the first time and let my daughter run around planting some. I noticed there's a big long line of flowers up the road from me, doesn't seem like it's some please someone else could have planted them. Are these normal or did some actually walk this huge area in the middle of nowhere to plant these?

Thanks in advance and also could someone tell me what the point of privacy zones are? Just to keep someone from tracking where you live?
