Really? Don't show up as a stranger or a single - Silverstone doesn't want you there. The employees always seem bothered that you showed up, from the front desk to the cart jockeys, to the starter.
I like that the course doesn't overseed; it makes it a good option for the end of August. But the course is not very challenging - it just LOOKS like it is. The three courses should help speed up play, but rounds here can go to 5 and a half hours. For their prices you can tee up at Badlands or Bear's Best and be much happier.
