So I have til June to travel on weekends , my weekend begins on Friday

and I'm enjoying it as it will probably never happen again...
anyways, I am starting to put an itinerary together. Given the cold, I guess I'll start in the South and work my way north as temperatures warm up... when will that be anyways? I wan to see SUN and warm temps ( I went home to DC for a couple of weeks recently, and they had unusually warm weather-T-shirts and all!)
so, suggestions as to where to start and how to work my way around. Obviously been to Istanbul and towns near Ankara.
Thanks
Marlene
