Hello. I am planning a trip to Crawford Hill this summer. Has anyone been there recently to answer a few questions I have? According to DeLorme's Atlas of Nebraska, there are no roads very close to the tracks around "White Clay" and "Windy Point" horseshoe curves. Are there good spots to get good photos of the curves? I have a 70-200 zoom lens. Do I need a longer one or will it be enough? Any help will be appreciated. Thanks.
