I’ve attended this event the past two years, but couldn’t make it this year, for lack of time, funds and justification. I also was demotivated by the cancellation of the Lunar Landing Challenge (which was recently reinstated), which was held in conjunction with it.
I’d actually like to go now, and I could afford it now, but I’m busy, and a last-minute ticket would have been pricy. But Clark Lindsey and Jeff Foust are attending, and will no doubt be providing updates over the next couple days.
