A: Hay bales exist in the first, second and third dimension, exclusively. Hay bales cannot travel through time.
I'm sorry to disappoint you. I know that your brother's death in that flood still haunts you, but you have to face reality: You can't save him by sending bales of hale back through time.
You'll have to think of something else, maybe a personal time machine, maybe a letter that can travel through time, maybe an enchanted Etch-A-Sketch that lets you draw the world as you want it.
I don't care what it is, as long as it keeps you occupied and out of the house. All that mourning your dead brother crap is really killing my buzz.
