The Zoo is very nice, specially if you have kids, you can choose between walking or going on the monorail which stops in each one of the main attractions....I like that! I think you get a discount as a Fl resident.
There is also parrot world, monkey jungle, butterfly world and of course the keys, also the museum of natural history and planetarium are pretty cool, I could go on and on but I guess it depends what you like doing, I find this city to have a good mix of things to do, oh, I forgot if you come with kids try Wanadoo city, my kids love it, a little expensive but once inside they could be the whole day inside with a ton of activities and it is located inside the Sawgrass mall so you can go shopping while they have fun.

Well it's not really that Miami sucks, but your roads are insane!!!!! We drove over there yesterday and got so lost, we ended up somehow driving through the ghetto and through tons of construction, then we somehow got in a traffic jam. We we got to south beach though,b ut it was like 5pm when we got there lol On the way back we got lost in that big highway clove loopty loop thing and there were so many cars and everyone was driving crazy and and and and i almost had a heat attack!! Thank god i wasn't driving or i would have pulled over and i would still be sitting in the car refusing to move. Ok now that i got all that off my chest, lol All i wanted to do was go to the zoo
Oh well next trip will be better planned and i'll have to stop at some of the LFS too and hopefully i'll make it to the zoo 
The only thing i hate about over here is no one owns a car under $200,000 (i'm exaderating. (i can't spell) ) and they drive psyco, but you don't want to hit one of thoes, because they probally cost more than your insurance will cover. But at least there isn't the big huge clover loop things lol
