My economics depend on where I am going and how long I am going. A few times I brought along camping gear only to find within a few nights that after riding all day in the rain, what I wanted most was a warm, dry bed and a hot shower (or at least warm)... and good local food. I love to eat and love to try the food of wherever I am. So, my day-to-day costs can vary: rooms can be from $25 to $150 per night, food may be from $10 to $50 per day. Then there is the cost of getting there which can be a few hundred dollars if it's somewhere in Canada or up to $1k to $2k if it's further away. So, what I do to make sure I neither skimp nor break the bank is take an average of lodging (~$40/day), food (~$25/day) and $1000 for flights. If the trip is short, I budget $100 per day plus flight; if the trip is long, I budget $100 per day in total. My hundred-day trip cost within $80 of $10k.

To keep the overall cost of touring down, I use air miles to cover the really long-haul flights.
