Note
The last 2-3 days of our vacation I began to notice some minor cold symptoms - mainly some coughing. Once we got home, the symptoms got worse and it was clear I wasn't going to get away with a minor cold. Oh well.
On the bright side, it was pretty much ok during vacation and the cold seems to be unpleasant but not overwhelming. I'm a bit tired, but not so tired I can't read, watch TV, or think.
One thing I've done to pass the time when I can't really do much - learn more about QGIS. I've been working on a big map of Yellowstone. We took the maps with us on vacation and they were useful - more detail than the park's ski trail maps. Yesterday, I worked on a NDVI layer (Normalized Difference Vegetation Index) from landsat images. Fun to learn something new and get results that look useful.
I slept 11 hours last night and feel a lot better today. But, still not well.
