Almost completely right, but please let me add that if you want to
learn the most valuable living Scandinavian language, learn Swedish.
Modern Icelandic is a wonderful language, and its morphology, grammar,
and syntax has remained almost entirely in tact from the form people
learn when they study Old Norse, i.e. "classical" Icelandic. The
reason I recommend Swedish, is that, although lacking in most
grammatical remnants of Old Norse (the extent is not as much as many
people claim though), it's vocabulary is largely intact and its
accentuation and intonation is very conservative, more so than Bokmål
Norwegian and Danish. Nynorsk is somewhere about 3/4 to Bokmål from
Old Norse, but definitely preferable if you want to be able to speak
to about three times the amount of people as those from Iceland (it is
an official language of Norway, but it represents only about 13% of
Norwegians). Swedish, on the other hand, has only one significant
dialect (at least in the sense that it may be transferred with no
significant difficulty to every living dialect in Sweden and Finland).
German is a good option as well, since it is a little less difficult
than Icelandic grammatically, and it is spoken by the largest amount
of speakers in the whole of Germanic languages (excluding, of course,
our own language, English). German is also West Germanic, and if you
learn the 2nd sound shift and take a formal course, you can learn it
with just a little work. German is also offered at many high schools,
community colleges, community centers (German-related institutes),
universities, and so forth. Plus, most of the American "Caucasian"
(that means white people, if you're dense) is of German-descent
(meaning we all have a little Kraut in us, more or less). French is an
important romance language, but will get you nowhere with Germanic
languages, Spanish just as little (despite some significant amount of
nouns from Germanic Visigoths). Latin will teach you grammar, but if
that is all you want, why not German instead? Faroese is wonderful for
philologists and Scandinavists, but even less people speak it than
Icelandic, and it is only a bit more conservative than Nynorsk. Modern
Icelandic is still, by an insanely large degree, the closest living
descendant of Old Norse. Take this word, for a random example, in Old
Norwegian: 'sjónhverfing' - "optical illusion," has change in Modern
Icelandicto 'sjónkverfing.' The only change in pronunciation is that
the initial sj- has changed from s- and j- (pronounced like English
'y' in yes) to Danish and Norwegian sj- pronounced like English 'sh.'
And the other change, h to k is noted in the spelling. There are
numerous examples, but if you can read and write Modern Icelandic, you
would have the greatest advantage available to read an older form of a
Germanic language in the North Germanic branch. Think of it as Old
Icelandic (a dialect of West Norse, Eastern Norwegian) with Danish
pronunciation. Lastly, although I love the Danes, Danish culture, the
country of Denmark, their language is ridiculously terrible sounding
and hard to understand when spoken.
Swedish is still the best option to learn as a modern Scandinavian
language. In relatively little time, a moderate level of mutual
comprehension can be obtained for the other two, Norwegian [easier]
and Danish [easy to read, almost impossible to understand]).

So in summary, the best three options are: 1) Modern Icelandic, 2)
Swedish 3) German. Although I'm sure a few people will debate the
positions of 2 and 3, if you want to get closer to Old Norse, that is
the best recommendation; that, or learn Old Norse and leave it as a
dead language you can only read and poorly pronounce and reproduce
(like in shows on the history channel).

If you're taking language courses this summer, it's unlikely they'll
have anything worth wasting money on. Save it until they offer German
or Old English.
