CNYIRA conducts actual wheel-to-wheel car races on frozen lakes
in upstate New York (the Finger Lakes, Honeoye, Oneida, Sandy Pond,
or any other place that freezes in the neighborhood.)
This is road course stuff, not oval racing.
Obviously, the racing doesn't take place unless the lakes
are rather hard, and easy to drive on (frozen, actually.)
Racing starts as soon as a lake has a minimum of 12 inches
of ice on it. Racing continues until the spring thaw,
or perhaps a little bit before.
Ice racing is the best value in wheel-to-wheel racing,
in terms of dollars per seat minute. Join the club,
and run your first race weekend for less than it costs
to buy a couple cases of beer and a couple of pizzas,
which is what you'd need to find another way to have
this much fun in upstate New York in the winter.
There are classes for full-on ice racing cars, and classes for street cars.
Contact is strongly discouraged in the street classes (similar to vintage racing rules),
so that street drivers can drive home at the end of the day.
