> In (3), if the bike is a tandem, is "you" plural or singular?
Singular. So I get one tandem + 1 piece of checked baggage, and Lisa
gets 1 piece of checked baggage.
The tandem and the bike case would weigh 75 pounds, so either my piece
of checked baggage gets the wheels, etc., or I pay $100 for a Santana
Cardboard box.
