John Garner laid out the community in 1842 and for a time it was a rather important shipping point. The old town site is now under water. It is interesting to note that the area in the vicinity of Preston is part of the Old Spanish Land Grant. Reynoldsville Reynoldsville is a small community at the south end of the Union County Conservation Area. At one time the Reynoldsville Ferry across the Mississippi River operated a few miles west of the village.
Today there is a church and a community building to serve a handful of inhabitants.
A small store also present is geared to the hunter and fisherman. Saratoga Dr. Penoyer, who founded Saratoga in 1841, envisioned another Hot Spring because of the mineral spring found in the area. A large bathhouse, hotel and swimming pool were constructed, but business was slow, apparently because of excessive prices asked by the owners. The land surrounding the spring was declared public property by Dr. Penoyer, and today serves as the Community Park. The spring is now capped, but a water pump provides a taste of the strongly sulphurous water.
