A long-time friend of mine, Mike Dorn, was married in San Juan last month. Kati and I decided to take a short trip to San Juan to the wedding and see a city neither one of us had ever been to before. San Juan is the capital of Puerto Rico, an unincorporated territory of the United States. San Juan was founded by the Spanish in 1521. San Juan is the 2nd oldest European established capital in the Americas. San Juan is very cosmopolitan and has really awesome beaches.
