The Beypazari Festival has started and will continue through Sunday evening. There will be many concerts, exhibitions and activities. There are also booths selling local food,arts, crafts, and other items.
Beypazari is a tiny, lovely village, full of restored Ottoman homes, approximately 100 km from Ankara. I believe there are buses running there.
It is also famous for carrot juice, 80-layer baklava, and beautiful (and cheap) silver jewelry. Below is a link to photos I took several years ago in Beypazari.
