Read the first case (Pennoyer v. Neff, 95 U.S. 714 (1877)) and consider the following problem for the 1^st day:

 

Allen Appleby bought a large quantity of German beer mugs for a Colorado ski lodge that he owns. Unfortunately, he did not pay when the bill was due and thus owes a considerable amount of money to the Bernard Boener, the seller in Munich. Appleby travels a lot. His legal residence is St. Louis but he is rarely here. His principal assets are in Colorado where, in addition to the lodge, he also has a large ranch. He also has a condo in a coastal resort town on the Pacific coast of Mexico. Boener asks for you advice as to where he might bring suit to collect the debt.
