I have inquired and or made an offer on 3 different properties in the last 5 months with the intention to make a Practice / Race track (mostly race) within a 20 mile radius of Dayton.
People either think their land has a gold mine under it and will not come down to a reasonable price. Or when you ask the zoning office about making a motocross track they get that "How can I screw this guy so hard he leaves." Look in their eyes. Lets just say this process of obtaining land is not NEAR as easy as I thought.
Now if you want to put it out in BFE then no issues. Close by "planned expansion" (which, apparently is all the way out next door to BFE) then the process hits brick walls everywhere.
BTW. want to learn something new? Stop by your local zoning office and ask for a definition of Agriculture and Recreational land use.
