Betty Ford indicated last night that she does not favor blanket amnesty for Vietnam war draft evaders.

Speaking to reporters aboard Air Force I, while she and the President were en route home from a two-week vacation at Val, Cole, Mrs. Ford said that her husband's limited amnesty program was "very good" and that she agreed that people who had evaded the draft should "work for a couple of years for public work or hospital or that sort of thing."

"I feel that those mothers that lost their sons is the war would feel very upset by the fact these people just took off."

The First Lady was asked whether she had advised her husband about the amnesty request made by Jane Hart, widow of Sen. Philip A. Hart (D-Mich.), who asked the President last week to give blanket amnesty to Vietnam war evadrs in her husband's memory.

Mrs. Ford, who found it difficult to talk because of lazyngitis, did not answer the question directly but indicated that she opposed the request. When a reporter said it sounded like she was opposing blanket amnesty, Mrs. Ford replied: "That is the way it sounds."

The First Lady also was asked whether she minded being unable to attend an inaugural for her husband. who was narrowly defeated by Jimmy Carter in the November election.

"I have sat through too many and they are too long," Mrs. Ford said of inaugurals.

The President returned to Adrews Air Force Base last night after a two-week skiing vacation in Vail. Before he left the Colorado ski resort, Ford was given a lifetime pass to the town's ice skating rink and a wooden plaque inscribed "Skis to the Town of Vail," by Mayor John Dobson.

Ford thanked the community, where he and his family have spent the last nine Christmases, for their hospitality and said he would return to ski in March.
