I was camping in the mountains north india for a couple off months completely disconnected.. it was wonderful. I became a lot more present and aware.
Soon ill start backpacking hopefully ill end up in cuba. Ive seen documentaries where after america did a trade embargo the people ended up having to survive and is now leading it self sustainibility.
Feel free to contact me before your trip to Cuba. I can give you some tips on what to do and what not to do. Remember, it's still a Communist country.
