I keep saying "I should do this!" and then procrasting until it's only a week away at which point, duh, this is me, I'm not about to organize myself that quickly.
So I bought a ticket, and carefully chose the non-refundable non-transferable options.
Now I'm stuck with it, and so I'm going to go do it, in eight months or so when it's actually happening. That should be enough time for even me to get stuff together.
With luck, the X-thousand people who are likely to attend will be enough that I won't run into anyone who's avoiding me or vice-versa.
