As a reminder of when Formula One was noisy the FIA Historic F1s are at Brands Hatch next weekend.
Saturday is mostly practice, Sunday the main race day. I'm pondering the cheeky option of popping in on Friday which is an open test day and see what's in the pits and paddock for the price of a Kentagon Cuppa. The "Grand Prix Terrace" will be open which is the pit lane cafe.
