(This reply is definitely OT, but...)

In looking at your website, specifically about the size problem, I was 
reminded of something I read about many years ago.  Now my memory is 
quite imperfect, and this was probably about 40 years ago, so I only 
remember the generalities and not too many details.  It was a 
description of a nature trail somewhere in Europe (I think it was in 
Switzerland), which had a scale model of the solar system along it. 
There was a 6 foot (or probably 2 meter) sphere at the trailhead which 
represented the sun, and at the proper proportional distances along the 
trail were properly scaled models of the planets.  I thought this was 
such a fascinating idea that I've always remembered it.  I think the 
article I read was probably in Astronomy Magazine, or perhaps Scientific 
American -- definitely a magzine of that sort, but I've never seen it 
described anywhere else.  And of course, I have no idea whether or not 
this trail/model still exists.  Anybody else know about it?
