I was watching a trailer for a rally documentary earlier in which Ken Block remarked, "people don't realize how expensive a hobby racing is."  I realized it after my first track day so for my second time out I opted for one round at around $100.  For that kind of money I got a lot of hot weather, a screaming baby whenever open exhaust cars flew by, a decent lap time and few more things to fix on the car.  Good experience but yup, expensive. 


Check out my personal blog soon for more info on this and track days in general.
