I've been a member of the site Postcrossing, for a few months now. I've gotten 3 post cards so far. I just got 1 yesterday. I have 1 that I need to send out soon. Below the postcards are from Salt Lake city, Utah (the pink 1), Taiwan & Russia (the bottom 1).
It's kind of fun to see the different places that you get postcards from. Some of the stamps are really pretty too. I'll post more as I get them.
