We got another guy doing something similar although not quite as far. I think he's riding from Keene, NH to NY. He'll be talking with reporters, handing out DVDs of Derick J's Victimless Crime Spree video and 101 Reasons Liberty Lives in New Hampshire.
What others have done in the past is called the news media a day or two ahead of arriving in a given town/city and then done interviews with reporters. This helps publicize what your doing and why. You can then talk about the Free State Project, Shire Society, etc. The more publicity we get the more people that more the quicker we can accomplish the objective of a free society.
If you need marketing material we have lots of that and can send you some in advance of your trip. Calling into FTL would also be great! David will be doing that if I'm not mistaken as well.
