<human>: So I'm currently loan free and will be graduating in Fall 2012 (end of the world and all). After that, I'll have about 4 months before I apply and get accepted into PTA school. 

During those 4 months, I'd really like to go travel, seeing as I probably wouldn't have the chance or time to do so later in my future. 

Extra info: PTA school will cost 5K within the next 2 years (community college super close to home, so no rent costs) and I'm pretty much guaranteed a job once I graduate, so I still won't have much debt, school wise.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: What are the logistics of taking out a school loan for traveling abroad? How do you pay that off while you're out of the states? Is this even a smart idea?
