John D. Jenkins (D), incumbent, 43, of 14252 Forge Ct., Dale City, was appointed to the Board of Supervisors last year to fill a vacancy created by the resignation of James McCoart. He is coordinator of computer operations for the Fairfax County schools. He retired from the Army as a lieutenant colonel in 1980. Answer: I am an experienced incumbent with a record of action and results. I have extensive management experience at all managerial levels. I support elected school boards and have initiated action to study the traffic flow in the Dale City area with an aim to alleviate present and future traffic problems. I am working with the state delegation and the Virginia Department of Highways and Transportation to have the express lanes extended from Springfield to Quantico. I am a strong advocate of better educational facilities and higher teacher compensation for Prince William County schools. I strongly support industrial development in Prince William County and am working with the governor and the Washington Board of Trade to attract industry to Prince William County. Edward G. (Ed) Rodriguez (D), 34, of 14505 Fullerton Rd., Dale City, is vice president of the leasing company at Town & Country Buick. He is chairman of the Neabsco District Democrats and vice chairman of the Prince William School Board's Human Relations Committee. Answer: Unlike the incumbent, I have lived, worked, and voted in Woodbridge for approximately eight years. My children attend local schools and my business is located in Woodbridge. Since 1975, I have actively served the public through several business and service organizations. While Dale City has grown, it remains essentially a bedroom community. The continuing demand for upgraded or expanded services and facilities to meet the needs of a growing, highly mobile population requires local government affairs to be conducted with a keen eye towards the future and with a realization that the revenues for such services must be generated from a sound economic foundation. We cannot continue to grow with unbridled enthusiasm or without a recognition of the finite revenue-generating capability of our local residents and homeowners. With my knowledge of local and regional business and community affairs, I plan to work aggressively to attract light, clean, and high technology industry to eastern Prince William.
