The following web sites which contain information on the Mason-Dixon line can be found at the following URL's Columbia Encyclopedia http://www.encyclopedia.com/html/m/masond1ix.asp Map of area http://geography.about.com/library/weekly/aa041999.htm colloquial line http://freespace.virgin.net/john.cletheroe/usa_can/usa/mas_dix.htm There are over 24,000 references to the Mason-Dixon Line when you do a Google search. I've probably read about 50 of them. I've learned lots of interesting information about the area of the line but if anyone looks at the map and reads some of the articles I believe we can put this subject to rest.
