Leaving Kiganza

I'm flying out iof Kiganza today and into Dar es Salaam. Though that's terribly out of the way for my final destination of Arusha, transport here is such that there's almost no other way to get there, besides hitchhiking with truck drivers, which I don't think I'm up for. Arusha is about a 10 hour bus ride from Dar, so I hope to arrive Monday night and start planning my entrance into the Serengeti. Have to go catch my plane!!
