Here I am in front of the famed "Torres" in Torres del Paine National Park in Chile. Liam was a champion trekker. He trekked uphill three hours the first day, where we stayed at a "refugio" with bunk beds and then summitted this trail with me the following day, over a very steep boulder trail. After we got down from the boulder field, he fell asleep on my shoulders almost immediately and I carried him two hours back to the refugio. Ouch, me old back.
