Last summer, my husband, Bill, took me camping for the first time. At every opportunity, he passed along outdoor-survival lore.

One day we got lost hiking in the deep woods. Bill tried the usual tactics to determine direction - moss on the trees (there was no moss), direction of the sun (it was an overcast day). Just as I was beginning to panic, he spotted a small cabin off in the distance. Bill pulled out his binoculars, studied the cabin, turned and led us right back to our camp.

"That was terrific," I said. "How did you do it?"

"Simple," he replied. "In this part of the country all TV satellite dishes point south."
