There are rattlesnakes everywhere in areas I've lived all my life. I've never seen a live one. They do not seek human interaction. About the only way you'll get bitten by one is if you reach into a hole one is trying to sleep in such that it can't get away and thinks you're threatening it.
Kraits can be deadly in India. I've read that sometimes you cannot even feel their bite, but their venom can kill you.
