Its not all negatives on your playtime when kids come along mate as i discovered a few years ago ! 1. They aren't really that pricy to run and grandparents always spoil the first and sponsor to some extent if played right 2. Your Missus will be too preoccupied with sick, poo and sleep deprivation to leave you to get on with whatever fairly un-noticed
I'm at a crossroads just now. I may take up trackdays proper next year and possibly put the blade on track as I have a 6 month old boy and feel that it may be safer to stick to track for a few years. Also moving job and house/area again so finances may be another issue depending on what size of house I go for.
