In 1972, Budd was named the Executive Director of the Wyoming Mining Association, and the family moved to Casper, and then Cheyenne. He was particularly effective in economic development activities and tax policy, as the mining industry in Wyoming became a major force in both arenas. He remained committed to his community, serving on numerous state and local boards, including a term as President of the Greater Cheyenne Chamber of Commerce. In 1986, he announced his intention to run for Governor, and in a seven-candidate primary finished a close second. Despite the loss, he always called the campaign the highlight of his professional life - According to Wyoming News, Bill answered the loss with "we met the most incredible people, and made friends we have never forgotten."
