It seems like the Airbnb cash exchange is unlikely to work. I'm now thinking of getting/walking as far as I can, then finding a boat or airplane or anything out of the country. Maybe find a travel partner. Before I get out of range (cash for food to walk) of Havana, test if I can take my flight on a different date.
I find it much harder to travel in the Caribbean than on the mainland. Instead of a few larger countries that you can walk or bike or drive or bus etc. among, you have numerous small countries separated by water, each having its own laws, customs, money, etc., often bureaucratic, difficult (to navigate).
Some days are hard. Some days go more smoothly.
I like the flex difficulties of traveling more than the boring difficulties of stagnancy.
I've learned that "slightly farther" often means "much more".
Walked from Matanzas through several of the most beautiful towns I've seen on the planet. Nice people, in the small towns & countryside of Cuba. Shoes, etc., barely holding up. Mind, body feeling stronger.
Maybe write about adventure travel. I'm often the only foreigner where I go. Share this perspective. Maybe leave out explicit science, technology, etc., write about what I encounter.
Cubans often make their own fruit juices, sodas.
Electric bikes, scooters, gas bikes, motorcycles are popular here.
Toilet paper seems longer (per piece), which I like, as a doubler myself.
Cubans seem thrifty, by necessity.
