The Spreadsheet Nerd

I've been crunching numbers instead of doing homework for the past 3 days. If anyone reads the forums you'll see my posts about it. Right now our estimates are somewhere in the vicinity of $23,000 (I always estimate high to avoid getting screwed by.... well life in general). So now we are in the process of cutting back that number. We hope to be able to cut it back to a final number of $12,000. I think we can do it, mostly because we are an adventurous bunch that likes to go with the flow. Most of our travels will be vague and general, which will let us pick up opportunities for couch surfing, and other forms of free housing / work. We've done some looking around for information on these. But of course, nothing takes the place of real experience. If anyone has advice, info, or links for us, by all means share them. We would really appreciate it. In a few days I'll add a links page of things that are helping us plan our trip. Only 531 days left!
