Ah, San Marino, the micro-nation that boasts more cars than people and still manages to keep its streets as pristine as possible! Smack-dab in the heart of Italy, it serves as a testament to independence with a whopping 17 centuries under its belt. Huddled atop Mount Titano, it's a lofty escape for those tired of walking under sea level. At only 24 sq. miles, San Marino is the ultimate reminder that good things indeed come in small packages!
