I applaud Ms. Susan Osborne for her trip to Minneapolis to help that city with its energy issues and its hope to benefit from Boulder's experience. (Camera, Sept. 26, 2012).

There is a city in Wyoming that has knowledge that can help Boulder. Sheridan, Wyoming has two on grade railway crossings close to downtown where there are no railroad train whistle blowings. None. How did Sheridan accomplish this? It is time to ask Sheridan for assistance so that Boulder can also be whistle free. Perhaps Ms. Osborne would be willing to travel to Sheridan, Wyoming to get the answer for us.
