My friend Tara is a college student who spent last semester in Copenhagen, and took advantage of every spare minute to travel around Europe. The message on her postcard is a wonderful reminder of why travel is so important. There's a huge difference between reading history and seeing its traces in person.
The above postcard of the Berlin Wall is an apt 4th of July posting, if nothing else as a reminder of what the lack of freedom looks like.
Happy 4th of July, everybody!
