After a pleasant morning at sea, National Geographic Orion made her way into the Daugava River and docked in Riga, the capital of Latvia. It was a beautiful spring afternoon, a perfect day to begin our explorations of this lovely little city.  As usual we had several options of walking tours, a biking excursion and a visit to the Central Market before we came together again for dinner in a lively cellar pub where we enjoyed a huge feast, two performances of traditional music and a chance to participate in some Latvian folk-dancing.
