From CBC News:
Rx train seniors rail against drug prices
A group of U.S. seniors in search of cheaper prescription drugs pulled into Vancouver Wednesday, after a trip from southern California aboard the Rx Express train.

The pensioners made the three-day trip as part of a protest against high drug prices in the United States.

A group called the Foundation for Taxpayer and Consumer Rights has paid for the train. It wants the U.S. federal government to reduce the cost of pharmaceutical drugs to Medicare patients and others by allowing a national bulk-purchasing program.
