WASHINGTON (AP) — President Bush is tending to his country's relationship with Canada and Mexico one last time, trumpeting trade over the "scare tactics" of economic isolation.

Bush joins Canadian Prime Minister Stephen Harper and Mexican President Felipe Calderon today in New Orleans for his fourth and final North American Leaders' Summit.

This year's event has the intended twist of giving an economic and symbolic boost to New Orleans, which almost 32 months after Hurricane Katrina struck, is still recovering from the most brutal natural disaster in U.S. history.
