River Crossing Game
Crossing the rivers in the Old West was a dangerous task for a cowboy.  Drowning was a constant threat to livestock and cowboys.  Ferrying supplies across the river was time consuming and costly.  The rafts needed were often rickety and slow.  Ferrymen rented themselves and their rafts out for hire to help cowboys cross rivers.  Your goal is cross the river in as few moves as possible, being mindful that some things could not cross the river on the raft with others.  Another great Texas Ranch House Interactive History game from PBS.org
