You got it twalker! Knowing when to nudge is ESSENTIAL! The skill (as I'm sure you are aware) is all in the back - if you get the angle right, you can actually see over the top of the wheels. It looks really cool as well. Of course, before you can nudge, one must perfect the art of the hold. Not as important as nudge I'll grant you, but the first elementary step.
My fondest memory of the art of the arcade was also as a nipper. I was visiting a mate who (from memory) lived in some sea-side town called Sheldon. There was this bust machine on the pier. Every time I put a penny (it was an old fashioned model for the coffin dodgers) in, it gave me 3! I had made £5 within two hours! This is when I realised the system is out to get me. The manager came and chucked me off - and put an 'out of order' sign on it!
Anyway, I wasn't deterred! By 15 I had amassed £30 and was a regular in the chip shop.
I ofen wonder and dream of my early Sheldon experience. Is it still there I wonder? I've actually put an application in to The Silver Stream in Brixton. I'm gunna be the bloke who doles out the change while I eat donuts and fried chicken all day. I'm gunna get all the secrets from the locals! Im gunna be rich rich RICH!
