Latvia tomorrow

I just booked a last minute cruise to Riga, Latvia.  It is another one of those 40 hour cruises so I won't be gone long.  It leaves tomorrow night then we tour the city of Riga on Tuesday then return to Stockholm on Wednesday morning.  I know literally nothing about Latvia other than it used to be part of Russia but I will learn something while I am there.  I also heard everything is very cheap so maybe I'll get some new clothes while I'm out of pricey Sweden.  I'm finishing up my 3rd class right now as I am completing the final paper for it.  My next class starts in May which is the dreaded Swedish Literature class.  Upper division literature is the last required class I need to graduate and I saved it for last being my least favorite subject so hopefully it won't be too bad.
