Mark my words, Gaalkayo will turn into a buffer zone 50km wide from Bur Salah to Ceel Dhahanaan in the very near future.
You should start investing in Garcad.
Galkacyo is the fourth largest city in Somalia, we can not leave it. What we can do is restrict new building in the south of the city, and make sure all new building on our side is at least a mile north of the city center. Then gradually we will have separated ourselves off from them to some extent. We could also fence off the south of the city and keep the road open. leaving the city would mean losing what people have built for the last 26 years.
