The stray dogs of Puerto Rico

These dogs don’t look happy — and they’re not. While they’re on one of the most beautiful Caribbean beaches on the island of Vieques, they’re among the 200,000 dogs in Puerto Rico that were abandoned or abused and left to fend for themselves.

From polluted to paradise: Cuyahoga Valley National Park

If you’ve only visited the national parks of the U.S. west coast you have a very specific view of what national parks are: spectacular wonders of nature that were preserved before development had much of a chance to alter them.

But the definition broadens as you head east. A national park isn’t necessarily pristine wilderness. And if you can get past the fact that the water in one used to catch fire, beautiful scenery awaits.
