Who knew?

At Middlesex University today with number one son for his interview (went very well, since you ask). 9.00 registration and then left to my own devices until 12 meant I could go for a good old nose about. Got thrown out of Hendon Town Hall next door, but then found this in the grounds behind the main university complex. Who knew people would still build Real Tennis courts? and who knew they'd do it in Hendon!!!
