You can get them in Asia - but in Singapore there's a fine for bringing them on the subway system. *G* You can also buy it in various pulped up forms which are less offensive (the smell comes from the skin, I think). See also: icecream.

:P I'm totally going to check the supermarkets around my area now, there's lots of asian supermarkets, and see if I can't find some Durian candy to send you...
