All roads led to the Urban Legends Reference Pages. I’ve seen two pointers to this site to debunk urban legends this week, and I’d never seen it at all before. The writeups for the two stories I’ve read (about the 1895 exam and standard railroad gauge) have been excellent. Bookmark this site so that you can quickly and easily quash those whacky emails that your non-net savvy friends and family members are constantly forwarding to you.
