Hi Alyn,
Are you in England? After the first sentence I got lost, but the M4 sounds familiar from Top Gear. I watch it over here on Netflix. If you aren't in England, then this is just a post from another crazy American.
I never heard of these people, but my wife is in England right now visiting her daughter and grandchildren. Have you seen her? You have a lot of mazes over there. Everytime she visits, the go to a couple of mazes. I think that might be saying more about my wife than England.
Was "Stumblin' In" a big hit? I missed it.
Cheers, Wayne,

My disclaimer: Any reference to the Mazes in England have nothing to do with England, only my wife's fascination with them. She love bringing the grandchildren it them. But I think she loves them more. lol
