Vorschlag? - suggestion?

yesterday was a big day, i was out of the house, out of the city, and it was above freezing. i knew it was too many good things at one time. today, just as i was getting ready to go out to the café down the street and take a little walk around the neighborhood, it started to snow. not just snow - blizzard. it was 4 degrees this morning but it got colder as the day went on and now, well, i'm not going anywhere.

bad weather outside means i have plenty of time to peruse my bounty of travel books and find interesting things to do on the weekends. the next big trip will be to prague. i have done some research and read the prague section of the frommer's guide but i always like a little inside info about places i'm going to visit. i know there are a couple of people out there who have been to prague. any suggestions? keep in mind it is february, and eastern europe is having record lows. indoor suggestions would be most welcome.
