I envy folks who can pare it down to this level. We keep trying but when we are only home for 2-3 weeks every few months we don't accomplish a lot.
I would LOVE to have nothing but one suitcase full of clothes, my laptop bag with laptop and camera gear, passport and credit cards, cell phone. That is what we live with every day anyway - the rest of it is just crap I have to pay to house.
I asked a friend to do an "estate sale" for us - sell it all and just send us a check. He's thinking about it....
