Night-O at Buena Vista.
Weather was pleasant -- not cold at all, as it has been in previous years.
I had a *splitting* headache (mild migraine?) from just before I started working at the registration table until I went to bed. I felt kinda spacey (it was hard to find words, at times), but I don't think it affected my orienteering.
...except for when I aimed off from #4 as if I were going from #5 to #6. Luckily I figured it out before it became a total disaster.
I also was kinda disoriented approaching the finish -- I ended up way too far north, at our parking / camping area.
Very fun!
