Şarkışla ( SİVAS ) - Akbulut (Van)

Alaşehir ( MANİSA ) - Menemen ( İZMİR )

Menemen ( İZMİR ) - Niksar (Tokat)....

 Tokat-Trabzon

Trabzon - Türkoğlu ( KAHRAMANMARAŞ )

Türkoğlu ( KAHRAMANMARAŞ ) - Ulukışla (Niğde)

Offff! It was difficult to find city starting with "U"!!

 Sorry: I will give you one starting and ending with U:

Uzunköpru (Edirne province) - named after a long bridge, built by Sinan I guess?

Uzunköpru (Edirne province)  - Ünye (Ordu)

Dear Marionin, I wonder how you managed to find the one starting and ending with "U", huh??   Little cheating accepted (ü instead of u)??
