I think June 4, 2008 stands out for me because of the situation I was in. I had been sneaking peaks at the SPC site and the forums throughout the day. If my memory is correct, I hightailed it home (I walked through a patch of woods from high school to get home back then) and got to watch the bulk of it from home. Grade school made me miss a lot of good events
I think June 29, 2012 takes the cake for me though. Simply watching the reports coming in as it came over the mountains is something I'll never forget. I had friends who were on a boat in the bay texting me and acting like I was downplaying the whole thing. A few days after, a few of them reached out to tell me how right I was and how glad they were that I pretty much forced them back to shore.
