Back when your mother was dreaming up Mother's Day surprises for her mother, finding a massage therapist by ZIP code, on-line, was not an option. But it is now. Check out the American Massage Therapy Association's site, www.amtamassage.org (we did, and it's legit), and arrange for Mom to have a session with one of the association's certified therapists at home or at the therapist's studio. Prices vary around the country, but you can take your pick of Shiatsu, deep-tissue, acupressure, Swedish, or trigger-point.
