It is a big modern city that is quite cheap compared to Mumbai. M.K. Gandhi lived there for a good part of his life, in an ashram where he was training people for civil disobedience (that's an oversimplification, but it'll have to do).
We saw the Sun Temple, in Modhera, and it was pretty impressive. I'll post the pictures whenever I get connected to the 'net again.
We visited some sights in and out of the city. I had a good time with a brother from the church. He invited me over for dinner, and I played with his daughter while him and his wife were preparing dinner. I was able to more or less understand her, thanks to my 'super' Hindi skills. She was very eager to show me her toys, saying all the time "dekho, uncle, dekho" (which means "look, look" in a more or less respectful way).
It was disappointing in some ways, because I wasn't more with disciples, and because the group I was with was not as 'go-go-go' on the traveling than I am. Still, I'm glad I went.
There are some pictures I took that I'm putting online:
