A plea for advice from UK. My wife and I would like to take the Zephyr from Chicago to Emeryville. We arrive into Chicago from Minneapolis on the 3rd July and had intended to take the Zephyr out on the 4th. We are now considering celebrating Independance Day in Chicago and travelling on the 5th. Do trains run on the 4th? Is Independance Day like Christmas in UK - a public Holiday where all shops bars retuarants are shut and everybody has gone home -? Is Chicago a good place to spend Independance day or is it a better plan to be on a train. Any help will be appreciated. Thanks Jim
