The fat body was not doing well during the early morning walk in the campground. It must be time to rest a day was my thought. However even a long, long nap was not restful enough. After most of the day had passed; it finally dawned on me---- Altitude Sickness again. After checking the internet again about altitude sickness, the symptoms seemed correct.
My history is that at 6000 feet my body basically rejects any kind of physical movement in the same day as arrival at the altitude. At 5000 feet it takes a couple of days. Fort Davis is at 5000 feet. According to the internet sources, 5000 feet does not bother most normal humans. But this human is bothered. The cure is to go down lower.
About four pm a ride was taken down to Balmohrea which is at 3800 feet. By the time the Truck got me to Wild Rose Pass, altitude 4500+/- the head ache and nausea was gone. In another few minutes my energy level was back up to reasonable. Well at least it is known what the trouble is from.
Now that needs to be remembered when plans for locations to camp are made. Having altitude sickness is definitely not good for trying to have tooooo much fun. TheOFM.
