My first year in germany was spent in augsburg. In that time I learned German very quickly through necessity as no-one, well hardly anyone speaks english. As a way of learning the language, which is such an advantage, it worked quite well.
Even my german wife was often asked right out if she was an auslander because she has picked up a bit of my Scottish accent over the years.
Another thing, and this may only be my personal impression, but after living in a community for over a year, people wouldnt even respond to a guten morgen, in fact i was "der schotte das oben wohnt", despite my constant attempts at friendliness (invites for coffee, drinks etc ). I met more friendly and open people in 1 month of living in munich than all that time in various places Augsburg.
Enjoy the city, but dont ever expect to be accepted into a community as quickly as you would in munich.
