My pleasure! I heartily recommend it. I've had a lot of fun with it.

I now try to grab some postcards whenever I'm in a touristy place, but I've also had good luck finding books or boxes of postcards online from sellers like Amazon and Barnes and Noble. I was surprised and pleased, for instance, that Barnes and Noble's website carries a lovely book of postcards with photos of places near us (the Blue Ridge Parkway, to be specific) - postcards I'd never seen for sale anywhere on/near the Parkway itself. Very convenient!
