Dee Weygand, a single parent, told Virginia Gov. Gerald L. Baliles yesterday that a subsidized church-operated day care center in Annandale allows her to "to keep my job and not worry" about her 4-year-old son Travis.

Next door, Erma Kendall, 86, gave Baliles a cookbook she helped compile at her "second home," a day care center for the elderly operated by Fairfax County.

Baliles' visit to the centers, which share a building formerly used by an elementary school in Annandale, was a highlight of the second day of the governor's "work week" in Northern Virginia. His schedule focused on cradle-to-grave educational needs.

At many stops, the governor was bombarded with examples of needs and accompanying pleas for financial support. Unlike Wednesday when he unveiled a series of steps to ease traffic congestion, Baliles made few commitments.

At the Annandale Christian Community for Action day care center, he announced a Governor's Conference on Child Care for next spring and said he would name a corporate advisory group on employe initiatives for child care.

He also spoke at a fund-raising luncheon for the Fairfax County Schools Education Foundation, which has raised $2 million for special programs in the public schools; filled a time capsule at George Mason University's new science and technology building with high-tech products from area industries, and spoke at the graduation ceremony of Bryant Adult and Community Education Center in Alexandria.

He got more ideas about the region's traffic. After flying on an airplane provided by radio station WMAL, Baliles said he will ask the state police to figure out how to enforce restrictions on the high-occupancy vehicle lane on I-95 to avoid the daily traffic backups on the highway.

"Right now it's Catch-22," he said. During the morning rush hour, the shoulder of the highway south of Springfield is reserved for vehicles with four passengers. When police stop violators in the lane, they block traffic and defeat the lane's purpose.

Baliles also got a glimpse of the often competing interests of growth and preservation during a special joint breakfast meeting of the Loudoun County Board of Supervisors and the Planning Commission, held on the patio of a bed-and-breakfast house in the village of Waterford.

Supervisor Andy Bird, urging a speed-up in road construction, said that under present plans, "there won't be a nickel's worth of cloud dust" stirred up until 1991 on a planned widening of Rte. 28, the main road to the fast-growing area around Dulles International Airport.

While in Waterford, Baliles visited a century-old one-room school where students dressed in period costumes told him about student life in the 19th century.

When Baliles asked how things had changed in 100 years, someone whispered, "The roads were better then."
