I (and others) have only had one serious tryst with a TSE so far and it proved with no uncertainty that we've accumulated a lot of bad karma from our previous births, atleast as far as Eclipses are concerned.
I did learn a lesson for a change, that sometimes you should bank on your first intuition regardless of how irrational it might sound. My first intuition *was* to go to Varanasi - which indeed did witness a fantastic totality while Patna (which was to be at a cloud-minimum), Taregna (of the Aryabhata fame. Gathered 50,000 people to witness the Eclipse, including the Bihar CM. Was widely believed to be the best venue for the TSE), et al saw darkness and nothing else.
Our own Dibrugarh experience was pretty disastrous.
