In 2014 I traveled through/lived in 7 countries, and traversed over 34,000 miles. Here’s a summary of what I did, and where.
Although Gibraltar is technically its own country, it's also part of Great Britain. And kind of part of Spain. And almost part of Africa. I just visited for a day, but truthfully, you don't need much more than that to cover off the basics on this little rock.
Gibraltar is a territory that feels like an island nation, influenced by many cultures and languages. Oh yeah, and it’s a massive tax-free shopping centre.
