What track style and type are best for:
Profit from rentals
Profit from parties
Profit from weekly/monthly race entries
Smaller tracks cost less rent per square foot.
Grandstands and Hillclimbs work well for parties and rentals. They are also fun and normally are great for racing.
Drag strips can do well. But you have to promote drags. Just having a drag strip won't work. It will turn into a dust collecting shelf.
Commercial raceways can benefit from data and knowledge. What was true 25 years ago may still work. But maybe things change? If you knew that ovals made less money than figure eight tracks would that help? If you knew King Track raceways are more profitable than raceways with an Orange track, but the tracks that had Orange tracks stayed open twice as long. Would that help you with your business plan?
Commercial raceways don't have much to go on when you try to compile industry knowledge that is timely and accurate. Yes, some folks will share knowledge that is helpful and correct. Then the trick can be to get the new business owner to use the knowledge. Does anyone here think a news letter or raceway assoc. can be set up to share knowledge and concepts worth testing?
