i have the fondest memories of holi. my family are from kolkata too - nice that you're getting to see it.
We enjoyed it very much. I'd not seen Holi before as it's not celebrated in Tamil Nadu where I was last year.
Kolkota seems an amazing city, not at all like what you hear - my first impressions were that it's not so chaotic as Chennai, and cleaner. The architecture is amazing. I'll probably go again to see more.
(P) what's this?
