Why Build a Rotisserie?

• Pig roasts are great fun.  
• Any day can become an EVENT with fire, a slow-cooking pig, many friends (often with excited children), and some beer.  
• The rotisserie is the centerpiece.  Simple ones can be rented for $400/weekend.  
• My son and his friends are experienced roasters.  They wanted a special rotisserie.
