There are 3 waters with railroad ties on each side to protect the waters from my skills with a skid loader.  I have gates at these points so I can divide in half or again in four pens (2-83x36 and 2- 42x36).  When I first got the calves in I divided in half run the calves to one half set up the chute in the middle and ran them through to the other half.  Can't do that any more.
