Democratic presidential nominee Bill Clinton will attend a Boston rally Friday afternoon in what may be his final Massachusetts appearance before the election.

Campaign officials have not yet settled on a final location, but said the rally will be held outdoors at approximately 4 p.m. Friday.

Gregory S. Chernak '93, who heads Harvard/Radcliffe for Clinton, said that a significant part of his 700-member group will attend the rally.

"This is your chance to see Gov. Clinton in person," Chernak said. "It's going to be a thrilling event."

Campaign officials said they will probably announce the rally site today, after the Secret Service completes sweeps of potential locations.

Although most observers think Clinton will have no trouble winning Massachusetts, state deputy press secretary Cheryl Brolin said the gathering is still important. The rally, she said, should maintain campaign momentum and remind Bostonians to vote.

"Nothing is assured until people actually get out and vote on November 3," Brolin said.

Locally, Cambridge organizers yesterday planned for the remainder of the campaign. Organizers are working to pack Friday's event with Cantabrigians.

"We are sending our contingents to Boston," said Cambridge/Belmont/Watertown field director Kenneth Bamberger in a press release yesterday, "so that the national news feeds can feature Bill Clinton at the birthplace of American democracy, surrounded by tens of thousands of supporters."

Bamberger said a strong showing in the immediate area is important because although Clinton is running well, Republicans have won the commonwealth in two of the last threeelections and local Democrats need to balance theGOP vote in the rest of the state.

Chernak said Harvard students will be involvedin promoting the rally on campus and throughoutCambridge.

Local Clinton staffers also plan to placesign-bearing volunteers near frequently travelledroads. One such "visibility" will take place atthe intersection of Mount Auburn St. and FreshPond Parkway
