From the sauna of the Bombay summer to the oven of the real thing. I've never really had to handle dry heat for any length of time before. The most time I've spent in the interiors before this was a-couple--days-for-a-friend's-wedding kind a thing. And those times were spent, as far as possible, in close proximity to giant coolers and the like.
Advance notice of what I was heading into came when I opened the door of the Rajdhani to sneak a smoke. Just 9 a.m., but the sun was already doing its thing in no uncertain terms.
And even then, in that cauldron run dry, I could see people working in the fields we were thundering past. Makes one feel like a complete wimp, I tell you.
