Mr Floyd, you didnt mention at all where the trip is planned.
Is it biking through outer Mongolia or riding down the west coast of the States? You realize the reason I ask is completely from a logistical point of view, if your trip plans are in a developed country with more or less regular access to towns, campgrounds, stores etc, then its not an issue. If it is somewhere where security and whatnot is more of an issue, then that's another thing.
It's around there perimeter of lake michigan. We live in chicago
