Jenkins is correct - it is India - tho I suspect Bears "fish farms" may be partly correct . It's what they call a "tank"
It's one of these busy, successful places with a few million people that few tourists ever visit and people just get on with life - hundreds of them across Asia these days
Always seems to have been a trading spot but nothing important has ever happened here as far as I can tell tho' the town center was planned by the Brits
Air India, Jet Airways, SpiceJet and IndiGo seem to be the main operators here
