I've always wanted to plan my routes retro-style. Looking at the large maps laid down on the table and marking the roads for my next ride. But given my lack of time and knowledge and the presence of Google Maps, I've never done it and probably never will. But these past few months, I've wanted to get one of those Road Maps and mark the roads I've travelled on and the places I've visited. Also should anything happen to my phone during the ride, these maps may be a life savior.

I have tried searching Google for Images that I can download and print on an A0 sized sheet but either the resolution is not high enough or the map is inaccurate. Also certain online stores like Indiamapstore are charging Rs.3000-5000/state for such a downloadable image, which in my opinion is too much.

It doesn't have to be the floor map exactly, atlases will do too...
Does anyone use these maps or atlases? Do you know where I can find them, either offline or online? It would be a dream come true, if I can get my hands on one of these maps.
