I was a bit nervous about going to Kuala Lumpur, after other tropical capitals I've visited didn't exactly leave a great impression. I'm mainly talking about Cairo. Dirty, noisy, stinky, sexually harrassy Cairo, which I had nightmares about for a week after I finally got out of there.
It turns out KL isn't as bad as Cairo, but even with lots of green around and a cool sci-fi monorail zipping above the Frogger-style traffic, I still prefer smaller cities any day. Unless they're Kota Bharu, obviously.
