Swarming visitors are a boon and a bane for an Asian Shangri-La

I enjoy my travels to Bhutan. The country's capital, Thimphu, reminds me of my school days in Kalimpong, a town in West Bengal that has since fallen victim to development. But am I also starting to see the same thing in Thimphu? Its streets are now becoming crowded, with many cars bearing Indian license plates as tourists flock to the mountainous kingdom to beat the summer heat.
