DEAR ABBY: Last year, my sister gave me a large plastic PLEASE CALL POLICE banner, which I kept in the glove compartment of my car. She said it could be a lifesaver if I ever had car trouble on the road, because I could get help without putting myself in danger by having to leave my car to seek assistance.

I took my car in for service a couple of weeks ago and had my banner folded in the glove compartment. When I went to pick up my car, the banner was gone.

When I asked my sister where she got hers, she said she had sent for it after reading a letter in your column from a woman whose car had broken down on a highway as she was rushing to the side of her critically ill child. She had placed her PLEASE CALL POLICE banner over her windshield, and it took only minutes for a state trooper to come to her aid.

I would like to replace that banner. Please tell me where I can get one. I am single and commute 300 miles every weekend. -- CHARLOTTE B., LAS VEGAS, NEV.

DEAR CHARLOTTE: Write to WCIL-BANNERS, P.O. Box 66955, Los Angeles, Calif. 90066. You will receive one PLEASE CALL POLICE banner as a premium for a $5 contribution to WCIL, and another banner with each additional $4 contribution. (Many people want two, one for the windshield and one for the rear window.)

Make your check or money order (U.S. funds only, please) payable to WCIL-BANNERS. Allow eight weeks for delivery. The Westside Center for Independent Living is a not-for-profit organization that helps disabled people live independently.

DEAR ABBY: Please help! My 17-year-old son, who just graduated from high school, has been invited to accompany his girlfriend's family on a month-long vacation across the country. As the girl's parents did not consult me before inviting him, I am now in the position of being the mean mom if I refuse to let him go.

As a registered nurse in the obstetrical unit that provides services for about 100 unwed teen-age girls a week, I am very much aware of the dangers of allowing teen-agers to spend large amounts of time together unsupervised. His parents will be there, but I'm very uncomfortable about the closeness this kind of vacation will provide. Secondly, we have a 15-year-old daughter, and I can't afford to set this kind of precedent for a similar situation involving her.

And finally, our son has a summer job to pay for his clothes and books for college this fall, and a month's absence would significantly decrease his contribution to college financing.

Needless to say, our once-quiet household is being torn apart by this situation. Please rush your reply. -- CONCERNED MOM

DEAR CONCERNED: Remind your son that he agreed to work this summer to help with his college expenses, so he can forget about accompanying his girlfriend on her family's vacation trip. And don't be apologetic when you tell him. His girlfriend's parents should have consulted you before inviting him. At 17, he is still a minor.
