When is the last time you received a postcard? Too long right. There is nothing like receiving a stamped note from far away destinations. Can you promise next time your away, even if it's a city next door to yours that you send a postcard. There are friends, family and loved ones who would be so happy to hear from you. Bring stamps with you and drop off at any mailbox. Last trip I didn't bring stamps and couldn't find anywhere I was, trying to run around before I got on the plane. I had to send when I got home.
