While Mardi Gras is actually on February 25th this year, there are already celebrations starting in Prague in January.  Together with the traditional annual zabijačka (pig slaughter festival), there will ba an early Mardi Gras Celebration at the National Museum of Agriculture in Letna.  Workshops, music, theater and dance performances in addition to a parade are part of all the fun.  There is an entrance fee, however, anyone that goes to the event wearing a real carnival mask gets in for free!
