I have 5 great roommates:
Daniel from Hungary
Alex from Germany
Adam from Colorado
Igor from Ukraine
Andrew from Cleveland
We have gotten along great and all of them would be people that I would hang out with in the states. I feel very blessed to have them as roommates. Also, the other people that are always around have been great. I've met people from Italy, Norway, Canada, Nederlands, Spain, Russia, among others.
Also, I have not had very much culture shock, virtually none. Prague is simply a big city. The supermarkets are very similar to the USA, they have WiFi everywhere, big modern malls and shopping centers, English is very common and there is every kind of food you could ever want. I had a different expectation that this was more or less an undeveloped country. I would say it was harder to get used to living in a city of 1 million people that adapting to the foreign culture. It has taught me that the world is not so different, but also shown me what I particularly enjoy about 'home.'
Here are some more pictures of the area:
This is the Castle at Karlstein (outside of Prague). This is a Castle that King Charles lived in sporadically during his reign.
Here is the village below the castle.
We walked through the countryside to an abandoned mine. It looks just like the country in America, maybe a little greener...
And here is the mine...
This is the Catholic church in Vysehrad, it is still used for services today.
Here I am with Prague Castle in the background.
