So I'm thinking about hiking the Appalachian Trail...

I've been wanting to go ever since I moved to the US, and I've got plenty of cash saved up just for this. We're (me and the wife) are going to rent out are homes until we get back so we can get some money while we're walking, and we're both going to work overtime every day until we're ready to go so we can keep our jobs.
It's 2175 miles long and passes through something like eight states. If I were to go I would start mid spring, so, no worries, you'll have me for at least a while longer... This will be one hell of a vacation.
