When I go on research trips...

I like to collect stickers.
you should try. PAGE ONE in HongKong is awesome for stickers. The HK people are all about the stationery.

so when I am hanging around airports. which I frequently do- this is a little task of mine. find more stickers.

but if you're still looking at PageOne check out this book...
