Sacrifice for the kid, eh? Good on you, Dad! Personally, I always liked the late-model A7SS, though I'd have liked a ride on the RGS, too. Next time I come to the UK, I'll see if they're still offering those rides...
What an absolutely outstanding thing that your national museum will do that. Here, they'd probably have to do an extensive background check, psychiatric exam, drug and alcohol screen, and for good reason. Otherwise, it'd be at least a two-weekend-a-month blood bath!
