Speaking Russian

So, I took 10 years of Russian classes in school as part of a proper Eastern European upbringing.  I recall at one point I thought I was pretty fluent in Russian.  Now, as I am looking at the official documents, maps, paperwork -- I am starting to wonder.....  Should be interesting.  I can still read the Cyrillic alphabet  -- so I'll be able to read the signs (?). I can probably get out basic sentences on what I want and how many, and where is it, and how much it costs....  Probably.  Gone are my hopes that I'll be able to understand what my interpreter and the officials are discussing.  I also got a little basic Russian workbook to brush up and refresh.  And a lot of stuff is coming back.  However, I am starting to realize that Communist classroom Russian and basic how-to-get-around-in-Moscow Russian are not the same thing.  I never realized that we didn't learn the names of fruits and vegetables.  However, I know the names of all kinds of farm machinery, and industrial equipment.  Thinking that reciting the twelve points of conduct for young pioneers, or the words to the Soviet national anthem are not going to be particularly useful.  I also can recite the story about the little boy who goes to visit his grandpa in the countryside, and asks him in amazement:  "Grandpa, this is your combine"  "No, no, my grandson, it is OUR combine".
Yes, it should be very interesting.  Bring it on Moscow.
