What would it cost roughly to build a covered, small velodrome? The reason I ask is because I know a guy who is seriously thinking about spending $500,000 on a sports car. I bet he's good for a couple million if he could put his name on something that would make him a hero in our city. Land is cheap here so I'm thinking strictly about the building.
Also, what do you think would be the shortest feasible track that a fit 50yr old could ride on?
