At the AIDS Memorial Grove, a ceremony led by Congresswoman Nancy Pelosi, author Armistead Maupin, and actor Judith Light combines remembrances with a presentation honoring Irene Smith, a volunteer massage therapist for AIDS patients since 1982 (11 a.m. Tuesday, Golden Gate Park, S.F., 750-8340; free). Meanwhile, the artist horea, whose previous World AIDS Day projects in other cities have included "AIDS Surviving Kits," has inscribed hundreds of red balloons with the words "December 1" and "World AIDS Day/A Day Without Art" and then metaphorically trapped their flight within the gallery walls for the exhibit "Ephemerals: 10 Years After." Local AIDS service agencies will distribute material and viewers can light a candle for a lost loved one (reception 6 p.m. Tuesday, exhibit through Dec. 8 at the Luggage Store Annex, 1000 Market at Golden Gate, S.F., 255-5971; free).
The Artists Alliance Against AIDS presents a special selection of plays from Pieces of the Quilt, including Tony Kushner's "A Prayer" and Migdalia Cruz's "Wednesday's Child."

And finally, activists, nurses, and politicians agitate for Alameda County needle exchange funding at a World AIDS Day Candlelight Vigil (5 p.m. Tuesday at 1221 Oak St., Oakland,  568-1680; free). (
