Somewhere along the last 13,000 miles of Latin American roads I saw an overlander carrying a dog stuffed into a plastic 5 gallon (that's 20 liter) pail lashed to his back rack. The lid had a cutout which neatly fit the dog's neck, and it appeared to be sitting there willingly (though who knows what it perceived as alternatives?). Sorry I can't remember more details, and sorry I (as usual) neglected to document on film.
Ewan, characteristically, is a dollar short and a day late. Plus, he's way overdue to lose the support wagon and hit the road with his dignity intact.
(from Puerta Natales, where the sun is out and it's easily 7 degrees warmer than Ushuaia, which is descending rapidly into winter)
