Where is the most interesting place you’ve been?
I consider "interesting" as new experience, and different from me.
Answer Progreso, Mexico. Seriously poor town. the Cruise ship rolls in, escorted by military attack jet boat.. Go through their fence, armed guards dogs. tanks.
get on a rickety bus to town. It goes by schools that are in session, that are solid cement, and barred up. but the kids are smiling as they enter, and in uniform. Were accosted by mexican travel salesman on the bus. Walk through a straw market. In the back of every store there are american drugs, that are free of beauracracy we have here, and well below
the price. got Panhandled by a dude with no legs, who was a marvelous flamenco guitar player. (he wouldnt let me play it lol) we buy a package for free beer for 2 hrs. cost 20 bucks each. and sat on the beach, then forgot about life.
Couldn't get much different for me. Learned a lot that day.
Special mention to Rural montana. where the ranchers showed up on horses, with rifles on their backs, and a pair of yamaha rhinos carrying supplies, they were moving cattle south out of the mountains. Rhinos needed gas. Cool perspective change for me.
