Just a heads up,
I'll be attending Railfest at the National Railway Museum, York, this coming Friday and Saturday.
I'll more than likely have some of the promotional postcards I had for the London Book Fair with me to hand out to anyone who'd like one, and possibly some promotional material for the book too.
I do envisage spending the days with my friends, but feel free to approach me if you have any questions; I'd be only too happy to answer and have a more general chat.
I would emphasize - most of all - enjoy the sights and sounds of what promises to be the Glastonbury of the railway world! I know I will.
