I've taken two classes on Russian in college. You won't get advanced, but it's a good start and I would like to continue on my own someday (and relearn some of the things I've forgotten since those classes). You'll have to get used to a few different sounds, but it can be done. The alphabet can also be done. The hardest part for me are the number of conjugations that can be had for verbs and, I must say this, reading handwritten (which is in cursive) Russian letters, since some of them will look so similar, especially if written in combination.
Basically, it's these letters, when handwritten:
ж (less so here because there is a difference to how it is written than the other letters)
и
й (less so here, because of the mark on top and because it's often the last letter)
м
п
ц
ш
щ
I find it will be much more useful for me here in New York because of the large Russian community, but it's also good as a personal interest as well. It's really up to you.
