Lots of towns have a “solar system” walk, but I had never actually done one before, so since I had some time to kill, I decided to give Gainesville’s a try. Of course, it starts with the sun.Gainesville Solar System map.This is the last marker. There used to be one for Pluto to the left here at the end of the trail, but they must have removed it after it was determined that Pluto is not actually a planet (or is it?).
