Road Trip

I am back from my most recent roadtrip. I loaded up the Tesla and started letting the hands-off Full Self Drive (FSD) supervised take me to points North. First stopping in a campground in Tennesee and up to Pittsburgh for the CIDM Convex Conference (which was the best conference in years). There was a celebration of the 20 years of DITA XML. I was an earlier adopter. My presentation went well and I semi-stealth launched wisdomino. I demo'd some extra cool software we developed and will be selling in weeks to come. It's truely game changing. Of course, there will be much more than that to come. After that it was on to Franklin, PA. to meet with some colleagues in the mining division and onto the farm stopping in Olean NY for the night. I am pretty sure it was the first time I had driven across the entire Allegany National Forest. I ended up driving through the very dark forest expanse during a night time thunderstorm. Although I normally trust the Tesla FSD on the Interstat...

In the following picture you will see a very interesting phenomena. The plane is above the clouds with the sun behind. You can see a shadow of the plane, but the more significant thing is the perihelia around the shadow. It was the day for that image. I had several opportunities for pics and I took a little film as well. You can see two distinct rings in the pic. The plane has a relatively sharp edge and the diffraction caused by the plane produces a nice series of rainbows projected on the clouds, I think. Very nice.

We call this a Halo in Hang Gliding. Every once in a while we'll get above the clouds (probably because we were towed there). I've seen my Halo once when I was in Florida... then we flew right through it!
