ARI SHAPIRO, HOST:
If you're vaccinated and looking to travel, Croatia wants you. The land of beaches and castles is one of the first European countries to open its borders to vaccinated Americans. NPR's Rob Schmitz qualified for entry and sent us this postcard.

ROB SCHMITZ, BYLINE: The Croatian immigration agent is not impressed with my flimsy paper CDC-issued vaccination card. It was filled out in blue cursive by a pharmacist at a Sam's Club in the U.S. more than a month ago, and it looks easy to forge. She's confused when I had my second dose. They write dates differently here.
