Free Range Cow Question

So I live in an intensely rural area, no neighbors for several miles in any direction, I've got free range law and am trying to decide on a dairy animal (between a couple goats or a cow), my question is will a cow come back daily at a consistent time if I supply it's only water source?? I've got lots of ways of getting my goats to come back but don't have personal experience with free ranging a dairy cow.

Sounds like you're set up to try it! Cows are curious and will wander, but also like the familiar most of the time. You might tray a small pen with milking area for a week with feedings, and gradually open up the outside during daytime only (between milkings). And get her used to a food call!
