I went and loved it, keep meaning to go back
backpacked/ morris oxforded around delhi/agra /jaipur rajastan, bombay
but ended up in goa , scored a royal enfield to ride around on it was fantastic, stayed a month
mind this was 15 year ago i expect Goa is shit by now on the main beaches, either find a quiet beach or go much further south
I expect calcutta or somewhere would be awesome.
get on the trains
I was eating and drinking anything i saw and was only ill a couple of times.
and as for the local conmen , they couldn't even outwit Jade from big brother so no worries there.

wear at leat 2 pairs of pants cos when i shit mine and threw them, next fart the trousers were a write-off
