not mary-land. Merr-uh-lin or Merrlyn. Depends what part of the state you're from. In the north they sound more yankee and say it in three syllables (though Baltimore is still Ballm're) but in the southern part of the state they tend to slur it into two syllables.

What I find interesting is that brits over-pronounce the names of places from other countries - mary-land or ice-land instead of the US icelun(d), but then you have leicester pronounced as a two-syllable word and warwick as warrick and such. british place-names tend to be pronounced not at all like they're spelled to an american, but then brits over-pronounce any place-name outside of britain.
ymmv, i guess, but that's something i've noticed.
