Michigan MDOT spent over 4 million dollars [[our money) on the circuit improvements on Belle Isle.
Why should the people of Michigan foot the bill for a race track for a billionaire?
Also, last weekend there were drag races on Belle Isle next to the fountain by a group of muscle car fans.
This park used to be tranquil, peaceful. but not any more. When these car clubs find they can do wheelies and donuts on The Belle Isle Raceway, it is no longer the people's park!
