How is it on a Friday morning? I have an interview at a studio at Elstree Way, Borehamwood on Friday at 10am and driving seems like it'll be a lot cheaper than a return train (£46 with railcard which is a full tank of petrol!). Not sure how bad the roads will be though as I've never driven around that area - anyone have any experience and would I be better off getting a train to save stress?
