When I first left the US three years ago, I was a nervous new long-term traveler. I had taken short trips out of the country before, but never had I spent such a long time away from home. I was so worried I wouldn't be able to find my favorite things overseas that I grossly overpacked, causing the scales at airport check-in to scream weigh-limit alarms.
Just a few days ago, at the check-in counter in Sydney, the aisles were lined with people unpacking & repacking, trying to get each piece of luggage under 20 kilos - exactly as I had done at LAX three years ago. It's nice to know I'm not the only one.
