Here at the city center they have a helium balloon you can get on, but I've always been scared 'cos 1) I HATE heights, 2) although it's tied to a rope, it's flown off a couple of times.
umm... simay... that's terrifying. hhaha. i've been on this balloon before and it was quite nice. sara and i took a few photos up there, too. but i never heard of it flying off and if it did, i'd be more than a little freaked out.
