Great stuff mate.. Often look at my own son playing the pins knowing that in years to come he'll be remembering it with affection - means nothing to him at the moment though.
Even at Expo i was on my stall and i think 3 times i heard a "THWACK THWACK THWACK" as someone beat the high score on an EM - remember smiling and thinking how those old girls still managed to shout above all the other machines.
Legendary stuff
