For the fourth time in five years I was a speaker at the RTMC Astronomy Expo at Big Bear this spring. My topic was Observatory Design & Construction, and was drawn from the three years of experience at GMARS building personal observatories. It was a great crowd and they asked lots of questions. I should note that my esteemed friend Ashley McDermott introduced me, and is seen in the wide shot, with his cane, in the front row.
