I am growing in a container and have not experienced any issues yet, but as for in ground, its just too damn cold here lately and even with protection trees are getting clobbered. I'd only go for it if you could build a fig protection cage or grew it in a microclimate such as south facing wall with a heat source nearby (I once saw a trio of fig trees survive the last winter without protection because they were along a brick wall and near a heat duct from the building's heat exhaust.) Without extraordinary measures, you are looking at annual dieback.
