Maybe it's spending all of your free time with your toes in the sand and a watermelon mojito in hand. Perhaps it's hitting up a music festival in a fun city, or even attending an adults-only sleepaway camp. Or, maybe, summer means an excess of free time: The three months of the year when things are just slightly more lax, and you can be less about work and more about play. No matter how you spend the hotter days of the year, it's always fun to take a peek at how others enjoy their own sunny days.
