Absolutely i agree - last I was there was nearly 10 years ago - my how time flies - but going over land from Malaysia to Thailand - I ate my way along - juicy rumpletums for breakfast, pineapples - well - anytime is good for pineapples : ).....
You've made me miss my old life

..... oh well, maybe we'll hit the road again soon - it would be a very different experience traveling with kids - one I would really like to have with them....
And as for pot luck themes - how about picking a fruit or veg as the theme - so each dish would have to have it in - an easy one would be avocado - but could do maybe something more unusual like starfruit or frejoia (can't think of any weird veg).
