I currently have the 2013 edition of the Milepost. Planning a long trip through Canada and Alaska this summer (2014). Do I really need the 2014 edition also??
Probably not; however, may I suggest another publication that we found to be even better than the milepost. THIS is the web page for it. Many of us who have used it on our travels to Alaska, swear by it. We hardly even looked at the Milepost after we got the Churches book.
Good luck and have a great trip. Watch out for those pesky frost heaves.
