Im with Lee on this one. I do this for escape-ism from life & work. The few weekends when I don't race, I am really moody on a Monday and the weekend drags big time - there is only so many times I can wax my car and doing anything else costs more than I can justify (id rather spend it on tyres!!!

)
It does gripe me at the cost, but only afterwards, while im racing I just want to escape from my emails, work, etc. and crack on with competing & socialising.
