"Surging gas prices and continued softness in the local economy undercut tourism activity this fall," said Dana Johnson, chief economist at Comerica Bank. "With gasoline prices well off their peaks, tourism might hold up better this winter, but sky-high heating costs could force some households to curtail their travel."
