Add Michael P. Amann right after Lenny Skutnik on the list of Northern Virginia's heroes of 1982.

While Amann's wrecking company was demolishing all that was left of Wolf Trap's burned-out Filene Center, phones in his Alexandria office rang off the hook with calls from Wolf Trap lovers ecstatic about Amann's offer to raze the remains for free.

"The response has just been incredible," said Amann, president of Wrecking Corporation of America, who offered to pay $1,001 to clean up what was left of Wolf Trap after the April 4 fire. The National Park Service, which owns and operates Wolf Trap, took him up on his offer, and Amann's crew moved in last week.

Amann said his office received letters from Interior Secretary James Watt and from a special assistant to President Reagan. "Two people called me on the phone and were crying because Wolf Trap symbolized so much to them," he said, "and some just called to say, 'I read about your offer and it brightened my day and I just called to say thank you.' " Then there was the man who wrote, 'If I had a building, I would hire you to tear it down.' "

Other Wolf Trap fans called to donate their services free for a day to help the wrecking crew, and still others offered free lunches for Amann's workers.

The 33-year-old McLean resident, who often had attended Wolf Trap performances, said he made the offer "because, like Pac-Man fever, I caught Wolf Trap fever." Plus, he said, "It's a matter of being at the right place at the right time in the right business. If I was in the shoe business, I couldn't have done it."

Meanwhile, although Amann expects the site of the Filene Center to be "broom clean" by Monday, he said he hasn't yet decided what he will do with the acres of debris, which by contract he now owns. Among the options, though, are several that could raise more funds for Wolf Trap, including sales of wood carvings made from pieces of the structure, metal sculptures welded from debris or pieces of the stage mounted on plaques.

And suggestions still are pouring in from all over the country, he said.

"What all this has made me realize," said Amann, "is what an oasis Wolf Trap was in so many people's lives."
