Speaking at Ignite Seattle 8

I'm going to be speaking at Ignite Seattle 8 on December 1st. Normally if I go talk somewhere (which hasn't happened all that often), it would be on Daily Kos related issues, but not this time. I'll be speaking on building an astronomical viewing shelter (which I need to write up for here too) on the cheap, coming in at about $100. You can buy a viewing tent for several hundred, or spend thousands on a dome.
