Here's the start of the map. This covers I guess around a month of the trip, which lasted 1 3/4 years and runs from the British Isles to Germany to Czech Republic to Austria to Switzerland to Italy to France.
Trip so far -- New York to British Isles to Cologne
Right now I'm entering the places in pretty raw but later I will go in a add notes to all the stops, revise the travel routes, etc. A lot of the author's travels were on foot so I don't even attempt to figure out the exact route. Other trips are on steamboat or early railroads.
Doing a little a day and seeing where it gets me.
Started the blog with one post and some links: http://viewsafoot.wordpress.com. Meanwhile relieved to find the book is already completely digitized and available online via Project Gutenberg and a couple other sources, so I won't have to scan or type any of it. Yay!
