here, it seems desirable for the bales to be packed tighter, maybe less humid air?? Also, there has to be so many hours drying time after a cutting. If dew falls on it or God forbid, rain, its usually sold as cow hay by reputable growers. But I have had some sell it to me cheap and say "its gonna go bad quick, it was damp when I rolled it" so we have to be aware of that.
We dont do any roadside grasses here, that kinda threw me too, altho my husband and I often discuss why doesnt the DOT allow hay people to mow the right of ways instead of tax dollars paying people to do it, would be good for hay people and horses too etc, and then we mused that well, maybe people would throw horrible things out of car windows that would be in it! Even drugs or anything! Janice -- even good horses have bad days sometimes.
