Actually, I am planning on starting a blog. In fact, I have been considering starting a full website for the trip. I am considering making it a benefit ride for the Juvenile Diabetes Research Foundation. I thought having a website might help in getting sponsors to help with costs and bring in contributors for the JDRF, while also allowing others to enjoy the trip vicariously. I've even thought about inviting a videographer along to document the trip. As far as I've been able to find out, nobody has ridden the entire GWT in one trip before. There are a few that have traveled over the entire trail, I believe, but I can't find any information where anyone has made it in one trip. Because of that, there is no documentation I can find as to how far it really is to go from the Mexican border to the Canadian. I plan to take a GPS unit and document my route, travel times, etc, for the benefit of future riders.
However, with all these thoughts comes the realization that the more people I involve, the more complicated things become. I would really like to keep things as simple as possible. If the benefit and sponsorship thing becomes too burdensome, I won't do it. In all likelihood, if I want a videographer along, I'm going to have to hire one. I'm not sure I want to do that either.
So, it may just end up a blog and a bunch of pictures. We'll see as I get farther along in the planning.
