This is my Dream Round The World Zoo Trip (DRTWZT) idea. So far this is only a dream, and not something that I know I am going to realize. The biggest obstruction as you know is money. However it is perfectly legal to dream big and plan the projects you dream about. And perhaps I even would be able to realize it. My idea is to travel around the world, visiting Europe, Asia, Oceania and North-America and see zoos and aquariums on my way. I would mostly try to limit myself to see the best zoos and aquariums in the countries I visit, (with a few exceptions). Since trying to see as many zoos as possible would take far to much time, and cost far to much money for me. I want to use Couchsurfing services as much as possible, to limit costs.
Here is the description of how I would like to travel: First is the Scandinevian zoo-leg. In the beginning I would buy a car in Norway, and drive through Norway and Sweden. From Sweden I would take a ferry to Finland, and back to Sweden again. Then I would drive to Denmark. Now I would have visited the best zoos in Scandinavia. Then I would drive through Germany visiting many major cities, and the best zoos there. The same procedure would be made for The Netherlands, Belgium and France. When I have visited the best zoos in these countries I would make use of the channel tunnel and carry me and my car to The United Kingdom. When I have seen the best zoos in the UK, I would sell the car or give it to anybody. I would fly a short trip over to Ireland, (and Northern Ireland). Then I would fly to The Iberian peninsula. Here I would rent or buy my second car, and visit the best zoos in mainland Spain and Portugal. Then I would fly to Tenerife, visiting some zoos in Tenerife and Grand Canaria. After that I would fly to Rome, Italy buying my third car. Then I would drive through Italy, Switzerland, Austria and Hungary visiting the best zoos there. I would then drive through Slovakia visiting no zoos. Then I would drive around Czech Republic and Poland, and The Baltics; Lithuania, Latvia and Estonia visiting the best zoos in those countries. I would sell my car in Estonia, after that I would fly to Moscow, Russia. After visiting The Moscow Zoo I would fly to Dubai, UAE. I would spend a week or two in UAE before flying to Dehli, India. All of the less developed Asian countries are rather less gifted with high quality zoos than the West European countries, so zoos would only be a secondary focus here. My focus in India and Thailand would be wildlife spotting and cultural attractions. I would spend one month in India, before flying to Bangkok, Thailand. I would spend another month in Thailand, before flying to Singapore. Singapore though is well stocked with animal attractions, so I would use most of my time there, and in the neigbouring Malaysia for that purpose. I would fly from Singapore to Sydney, Australia. In Australia I would rent my fourth car and visit all the best zoos in that country. Then I would fly to New Zealand and be there for some weeks, visiting some zoos there. Then I would take a flight to another country and continent, Los Angeles, United States. I would be renting the fifth car I use, and visit major zoos in California, Arizona, Oregon, Washington and Vancouver, Canada. After I have done that I would fly to Houston, Texas, visiting a few zoos in that state. I would rent yet another car in Texas. However the Texan zoos I visit are few compared to the huge amount of zoos that exist in that state. Then I would fly to Chicago, Illinois. And using a car as transportation I would visit zoos in Illinois, Indiana, Michigan, Minesota, Ohio, Nebraska and parts of Canada. I would also visit the state of Iowa on my path. I would then fly to Miami, Florida. And I would visit several zoos in Florida and Georgia, using a car

. Then I would fly to New York City, and visit zoos in New York, Philadelphia and Washington DC. This time using collective transport

. Then I would fly over the pond to Oslo, and to my beloved home country, Norway.
So what do you think about my trip idea? Do you have any advice regarding the idea. And are there any major zoos on my path which I have left out, that I would benefit from visiting?
