Cattle into neighbor's field

Today I let the cattle into a neighbor's field.  They would like their grass eaten down.  I'm fine with that.  Especially since the cattle had been standing in the corner of the middle pasture and mooing at me across the fence to let them into the south pasture when I started to lay out my irrigation pipes.  The irrigation pipes are stored in the south pasture, and having the cattle in that pasture while I move the pipes from the south pasture out to the hayfield would be a pain.  Now I can lay out the irrigation pipes tomorrow in peace.
