Ouch! Thats my first reaction. I've never heard of anyone doing this before. Here are a few things to think about. How long do you think it's going to take? How far do you plan to ride each day? What's the farthest you've ever ridden in one day? Do you have a long enough seat post to efficiently pedal while seated? How do you plan to carry the things you're gonna need? Backpack, panniers? I don't know of any racks that fit bmx bikes, and besides a rack on a bmx bike kinda defeats the purpose. Anyways, if you're serious about doing it and you make it that would be quite an accomplishment.
