I traveled to Izmir by myself this past Monday. I left Istanbul with less than 300 TL in my wallet (which is less than 150 USD/100 GBP) and no other access to money. I left with very little credit left on my phone and with only the address of my destination. I left without a plan.
By 9 pm that night, I was in the company of two Turkish men, an Italian girl, a German girl, and an Australian bloke.
