Pre-flight: 3 Days Out

Well... As many of you already know, I'll be spending the next four months of my life in Costa Rica studying abroad at Veritas University in San Jose.  There's now only three more days until I get on that plane and head down to warmer weather.  I would be lying to you if I said I wasn't a little nervous.  Mostly though, I can't wait to go.  The excitement and suspense of waiting is killing me.  Even though my Spanish is a little rough, I'm sure after a few weeks I'll be just fine.  I tried to start packing over the weekend and on Monday but all I really got done was getting my suitcase out and buying a few toiletry items at the store.  Goal for today: finish packing and then hit up the store with Peter to pick up the last few things I might need.  How many pairs of underwear and socks do you think I should pack?
