It's a fairly common past time for people interested in fast cars. It's comparable in price to a day skiing.

Same goes for off-roading. Luckily I live like an hour away from a big parc in Germany so my 1982 Range Rover can enjoy his natural environment at least a couple of times! Logically totally useless, but hell of fun!

There's a small track I can get on for $35, tho I won't hit triple digits.

Track nights can be as low as $125 and you will hit triple digits.

But yea, $125 is equally as out of reach as being dropped on Mars.
