The world looks pretty spectacular from 12,000 feet high, at least when you're in the Rocky Mountain National Park in Colorado. (Click pictures to make them bigger.)
We're spending a few days exploring one of the most breathtaking parts of the country, but it hasn't been easy for someone who spent the better part of his life living below sea level in New Orleans.
The effects of high altitude - shortness of breath, slight dizziness, headache, rapid dehydration, serious fatigue - kicked in around the 8,000 foot mark.
We ended our day-long treck through the park at the Continental Divide where water flowing on the east side runs toward the Atlantic Ocean and water flowing on the west side runs toward the Pacific.
