   This is an interesting twist on the ladder pole problem. However you   
   have the pole hitting the barn from the front not from left to   
   right. Well let us set up 5 bowling pins from left to right in the barn   
   and hit them with our bowling ball from the front of the barn. If the   
   bowling pins are length contracted then it will be a strike of all   
   bowling pins being hit every time provided the bowling ball is somewhere   
   in the middle of the barn. Nicely done.
