There was a recent article in USA Today about writing postcards. According to the article in 1951 more than 4 billion postcards were sent. Now it is down to 400 million.
Writing postcards is still one of my favorite hobbies. I write to people around the world via Postcrossing as mentioned in the article. I also send cards to a couple of hundred friends a few times a year.

Here are some cards I received from Lilli and Rebecca during their hiking expedition to Mt Blanc last month.
