Go to as many of these places as humanly possible. So far I can check off: Yellowstone, Lake Tahoe, Napa Valley, Zions, Death Valley, and Multnomah, OR.
Samos, Greece is popular for being one of the sunniest destinations in all of Europe! Pack your swimwear and plan to enjoy plenty of time on the beach and in the water when you visit!
