Stayed for an extra day in Hannover to do some chores and some shopping I needed, planned to visit some museums too. It turned out though that Monday is a museum holiday in Germany!
I tried to get a cheap lunch by visiting a supermarket, but managed to visit the most expensive organic vegetable supermarket in Hannover (if not Germany).
There was a beach volley ball tournament going on in Hannover too, which was pleasant to watch for a while.
Have realised that my planned entry to Russia on the 28th July is probably too late and I am more likely to get there on the 22nd June, will have to try and see if I can get the visa changed.
