Nancy Reagan has accepted the position of honorary chairman of the Wolf Trap Foundation Board of Directors. The board made the announcement yesterday at its annual meeting at the Department of the Interior.

"I think it's the first board in this area that she's joined," said Kay Shouse, donor of Wolf Trap. "She's not the kind of person to get into something unless she's really interested."

The honorary chairmanship of the 55-member board -- which oversees the activities of Wolf Trap Farm Park, the Virginia performing arts center -- has traditionally been held by the first lady, as it was by Rosalynn Carter. The actual chairman of the board is Edward Crosland, a retired senior vice president of AT&T.

In a statement released yesterday by the White House, Nancy Reagan, who did not attend yesterday's board meeting, said, "I have heard so much about Wolf Trap from people across the country. I look forward to seeing it in operation and becoming involved in its many wonderful programs."

Shouse first broached the subject of the position to Nancy Reagan during the inaugural events. "I had a chance to talk to her," said Shouse. "She's a very sympathetic person."

Shouse does not know what role Nancy Reagan may want to play at Wolf Trap. "We haven't gotten to that," said Shouse, "but she likes the concept of Wolf Trap. She hasn't been there yet, but she has a lot of friends who have."

The board also announced the appointment of eight new members, including Jane Weinberger, wife of Secretary of Defense Caspar Weinberger. She will become secretary of the board.
