Kathmandu to Delhi via Bandhavgarth, you decided to take the long way round then!
Mostly travelled around Gujarat (Surat, Baroda, Ahmedabad) but also been as far as Mumbai, Delhi, Chandigarh, Agra. Fascinating country with stark contrasts between those with and those without and some amazing countryside.
Travelling on the Shatabdi Express (I dont think it ever got above 30mph!) from Mumbai to Surat is.......interesting.
