I've always wondered if you're in a country or city - for example during a layover - if that counts a visiting. I was in a layover in Switzerland and was completely taken aback by seeing the Alps. Maybe next time I'll actually get the chance to ski on them.
On my bulletin board, the current places I have on my bucket list are:
Space? The Moon?
All of them are definitely possible but that last one---I'm not so sure. Maybe in my lifetime Virgin Galactic will become affordable.
Some other places I'd like to add on my Bucket List are:
There are also a bunch of places in California and the US that I have yet to go and it makes me a little sad because it's definitely possible!
Montana (Don't ask me why but I've always wanted to go there, Lol)
