 5. Places I have Visited so far: 

    Outside India:  

     Perth 2006, Singapore 2007, Sydney 2009, San-Fransisco

    2009, Miami/Florida 2009, LosAngeles 2009, Charlotee 2009, Malaysia 2010-11

    In India: In one word it is countless. Usually I love to trek across the 

    Himalayan ranges. I did it couple of times before ( mainly in Garhwal Region ). 

    Hope Once done with my work, I love to go back India and travel as much

    as  I can.
