Survival Equipment Becomes a Hot Topic

Sheral Harrison had barely unlocked the doors at U.S. Surplus in Phoenix when an unusual customer walked in.

Dressed in golf shorts and a Polo shirt, the man grabbed five chemical warfare suits for himself, his wife and children, along with gloves, boots and gas masks.

All day long, men in suits, women with children--panicked or livid--flooded the store stocking up on supplies in the aftermath of the terrorist attacks in New York and Washington.

Other Americans followed suit, as water and canned goods disappeared off store shelves and lines at gas stations grew as drivers scrambled to fill their tanks.
