I'm always the 'just in case' girl whether it's packing for a short/long trip, so needless to say I tend to over-pack!
With my upcoming trip, I'll need to pack for three seasons (I should be used to this having lived in Utah for a number of years). It will be Spring in Hong Kong, then going to extreme humidity in Malaysia and then to Winter in South Africa!
I start off with piles of what I think I need. Hopefully those piles will dwindle down to bare necessities!
Off to do more packing now!
