I am a European (Belgium) that traveled across the United States for months on my own. AMA
I visited 19 states, got culture shocked about every day, hiked through tons of national parks like yellowstone, grand tetans, arches, bryce canyon, zion national park, grand cayon, mesa verde (that is now closed indefinitely), ...
Lot's of recurring questions:
How much did it cost? - I spent 10.000USD. Could easily have done it on 4.000USD. I just went nuts a bit. Where did you go? - Main travel plan: NYC - Chicago - St. Louis - Kansas City - Denver - Roadtrip to Wyoming, south dakota, montana, Yellowstone national park, grand tetans, Idaho, Utah, All National parks in southern utah, Arizona, Grand Canyon, Colorado - Denver - Kansas city - St Louis - Nashville - Atlanta - Orlando - Washington DC - NYC. Of course also did everything in between and many side excursions with locals.
Edit 2: I love the response, never thought this would be of interest to anyone. If I missed your question or follow up question, please be patient or message me privately. I'm up to talking to anyone about anything.
Edit 3: Lots of interest in more pictures. I'll make public albums. Please be patient!
Edit 4: Soooooo many questions! Unfortunately I have to go right now (you know, time difference and all ;)). I will return to answer more in about 12 hours from now. Also, all the people I asked to contact me, please do! All the people that want to contact me privately, please also do!
Edit 5: Lot of people showed interest in my video of the Grand Canyon: Here it is! https://vimeo.com/47893337
Edit 6: general map of the trip. Is only roughly plotted out of course: http://imgur.com/Grn9N0V
Edit 7: I will keep answering questions, but please be patient. 7500 comments to go through is a lot! And my inbox is filled with PM's too. I will respond to everyone though.
Edit 8: For all people saying I forgot California. It was a choice not to go there this time. Only had so much time. I feel the west coast deserves its own multi month trip. Going to West coast is my childhood dream so it will happen.
Edit 9: OK, so I think I got every question. If I didn't respond to you personally it's because I answered your question already about 100 times. Sorry, but look through thread and you'll get your answer. If you still have questions for me, PM me!
