Should any one be interested I was researching locations for my Roughing It gazetteer, specifically Virginia City. It seems the National Park Service has references for a Pony Express Station in Nebraska referred to as the Virginia City Station. I had created an entry with a link to the NPS source. That link was broken and I could find no other mention of such a station. Eventually I found the correct link to this item, http://www.nps.gov/parkhistory/online_books/poex/hrs/hrs4c.htm#16 and corrected my link, but all other such links remain broken.  Just thought I'd mention it.
