haha my cousin and i did that in the winter and the bales were covered with plastic tarps held down with rocks and he ended up smashing his face on the rocks and breaking his tooth, pretty funny.
haha holy shit I just remember one time about 20 of us did this at our real good friends farm one night at about 4 am because we had been camping out on their farm down by the river...somehow we stumbled upon the bails and jumped around in this massive field
