On Oct. 1, Younghusband, a 61-year-old Vietnam vet who lives in El Cajon, Calif., will start a six-month journey accompanied only by his two dogs -- a Chihuahua-dachshund mix and a Jack Russell terrier -- and the aforementioned burro, whose name is "Don-Kay."
It's a dream trip for Younghusband, who has loved Baja all his life, but only became inspired to take the journey after reading a book by friend and Baja expert Graham Mackintosh, who accomplished a similar odyssey.
"I know Baja and love it, and when I decided to do the trip, I knew I wanted the burro," Younghusband told AOL News.
But not just any burro would do.
"I could buy a green burro, one that's never been ridden or trained to carry items, for around $300, but mine is trained and that cost me about $700 -- in Mexico!"
However, when it comes to burros, Younghusband quickly discovered it's a seller's market.
"There aren't that many burros for sale," he lamented. "I looked for months and I couldn't find one in San Diego, Los Angeles or Phoenix."
Fortunately, he got lucky about eight months ago and found Don-Kay, a 4-year-old burro at a ranch just across the border near Tecate, Mexico.
Younghusband has been going to visit Don-Kay twice a week in order to bond with the burro before the trip.
"When Graham made his trip, it was on a burro he met the day he started his trip -- big mistake!" he said. "I really want to become friends with him so that he trusts me. The hardest part will be leaving the ranch. He's the only male among a few females and he has kids and his own stall, so I will have to coax him along until we're finally away from the ranch."
After that, he says the hardest part will be keeping Don-Kay away from any females he meets on the estimated six-month trip.
"Burros roam free in Mexico, and that's a big concern of mine since he's an un-neutered male. If he hears a female, he goes crazy and ears go back on his head and he wants to get away," he said. "I've been through it before.
"It won't be easy dealing with that, but I didn't want to [neuter] him before the trip because A) the operation is difficult and risky for burros and B) there are more females than males, so I am hoping I can barter goods and services from farmers in exchange for letting him sleep in a pen with their females."
When Younghusband isn't hiking or pimping out his burro, he plans to hunt for quails, clams, lobsters, rabbits and other food found along the coast. Still, he has been preparing for the trip by visiting predetermined spots on the route and burying caches filled with items like whiskey, coffee, flavored waters and other goodies.
"I am also bringing along protein bars for Don-Kay just in case there isn't enough places to graze," he said. "I hope he likes them."
Younghusband figures he'll be traveling up to 10 miles per day, but some days, like when he reaches a mountain range or 100 miles of mangrove trees, he'll be happy if he makes it four miles.
"The hardest part will be the mangroves down near Cabo San Lucas," he said. "They go into the water and they attract lots of mosquitoes and flies."
Younghusband won't be completely out of the loop on his trip. In deference to his three daughters, he will be using a GPS messenger so that his whereabouts are known at all times.
"I know a lot of people who live in Mexico who plan to use GPS to meet up with me while on my journey for beers and such," he said.
Although Younghusband is taking the trip for his own enjoyment, there is a higher purpose to the journey.
Younghusband expects the trip will take six months, but his friend, Mackintosh, suggests it may not work out to schedule.
"My first trip was scheduled for around six month," he said. "But it took me almost two years. I was having so much fun and surrounded by so much beauty and peace that I was in no hurry to come back."
