Remember summer weekends? Like last summer? Lovely drives to the country to explore nature and the flea markets . . . to a friend's barbeque or picnic across town . . . to the Bay to go boating or crack crabs . . . to Rehoboth or Ocean City to get away from the city and tan the body. The only real hassles then were the Bay Bridge Backups.

Now every open gas station resembles that backup as the main weekend activity becomes finding gas for the weekend - and then being afraid to drive anywhere because it means facing another line Monday.

We may queue up for the lastest hot flick or Baryshnikov's flying leaps, but waiting for gas is another matte. Psychiatrists say their patients have growing feelings of helplessness, of being manipulated, and fantasies of revenge - particularly on anyone who cuts into a line. The love affair with the auto is turning into a hate affair with the oil companies. OPEC, politicians and anyone else between the driver and the pump.

To justify the time-consuming hunt, it's time to discover the joy of doing things you never would have done without the wait.

One woman cleaned out her entires car. "It looked like I lived in it," she laughed. As her car crept toward the pumps, she gathered more papers for nearby dumpster.

"Lady, how much more could you have?" wondered the stunned driver behind her.
