yeah I know you did not ask!
This “random thought” may be somewhat obscure to many readers, but to those of us who know JMR, it will relate immediately.
JMR takes walks regularly and drives quite a bit for various reasons. All of us in his circle are use to frequently getting calls from him at these times as he has had a thought he needs to share.
Reflecting on this, it is obvious to me that this is his method of sharing in the same vein as Rev. Joe’s Random Thoughts. The acorns do not fall too far from the oak tree. Of course his method has the advantage of not floating around the Internet to come back and bite him.
