I built this site 8 years ago, just as responsive design was starting to take off. Responsive themes were still a novel idea then, and a lot of sites were not responsive, so I saw no harm in building a non-responsive site.
However, I started having problems with the old theme, and I have had to change to a newer responsive theme.
So I will be making a lot of adjustments over time.
A lot of old posts will be off-kilter for a while.
