Some people keep a journal or scrapbook to document their travels, but for Louisiana-based backpacker Bill Passman, he prefers getting tattoos.
The story goes back to 2010, when Passman decided to tattoo the world map on his back after seeing a similar tattoo on a fellow backpacker.
Instead of tattooing dots on his map like the other backpacker, he decided to color in the countries he has visited.
According to his blog, he has traveled to Africa, Denmark, Sweden and Russia.
Check out his tattoo below:
