Interesting to have a map with colored pins to describe places you've been and places you've only been to the airport. You can imagine being on ship and sailing by islands, oceans, and actually being in a part of the world physically walking about under the sun that has no description of a place, just an ocean. Like going across the Atlantic and Pacific Ocean, that is very vast. Different climates and different skies. I have been to the Indian Ocean, Pacific, Atlantic, Caribbean, East China Sea, Sea of Japan, Mediteranean Sea, Straights of Gibraltar, Panama Canal, Suez Canal, many different bays, straits, channels, so it's hard to say I've been to these different countries without mentioning the parts and regions and oceans I've been to. Not to mention flying over regions like the North Pole and Greenland. Shipping differes from flying in that, in a plane you are in an enclosed craft pressurized in above clouds altitude. Shipping, you are right there experiencing the current climate at your location, feeling the elements, working under the sun, or walking on deck. You are actually physically in that environment no matter where the ship sails.
