Ashland Farms operates a wind farm just outside of Palm Springs. Ashland has 400 turbines operating in the area and the winds find the turbines turning nearly round-the-clock. Next to the outer ring of Ashland turbines is a subdivision, a retirement
community that finds retirees taking advantage of the Palm Springs winters and golf courses. Residents there are complaining because of the constant "whirring" noise that makes it difficult for them to sleep and often to hear radios, TVs, and computers.
