I've lived in France and California for a year each.
i'm really lucky that i went all over the US as a kid as i don't think i'm allowed to enter now.
in the US i've been to these states: California, Washington, New York, Pennsylvania, South Carolina, North Carolina, Illinois, South Dakota, Wyoming, Utah, Colorado, Idaho (just passed through...), Montana (ditto), Hawaii, and then whatever the fuck district of columbia is
Europe: All over UK, France, Spain (Barcelona, Valencia), Portugal (Lisbon), Greece- mainland and Islands, Germany (Berlin, Hamburg), Switzerland (Geneva, Alps), Italy (Milan, Florence), Austria (Salzburg), Poland (Warsaw, Gdansk, Sopot, Krakow), Finalnd (Rauma), Sweden (Gothenburg), Czechia (Prague), Croatian coast + Dubrovnik, Netherlands (Amsterdam), Belgium (Brussels)
Other: coastal Turkey, Japan, Cario+Luxor, Namibia, Morocco, all over Georgia, all over Iran, Grenada, BVI, Jordan, a few places in Brazil and Argentina, Mauritius
The majority of this travel was when I still lived at home, or through my phd studies where you are funded to present at conferences.
What do you wanna know about the UK? We have some fucking gorgeous chocolate boxy villages but most towns are shitholes.
Next I wanna go to Tajikistan, Uzbekistan (I had a trip booked to those two cancelled multiple times due to covid) and South East Asia. fucking broke right now and also just got back from holiday so not going anywhere for a bit.
