enjoyed playing though didn't solve it

Easy and pleasing
Liked the Bolingbroke group!

Very good. Ford was a nice red herring. Every item in the bridge group is a horizontal supporting structure in its own right (albeit that pontoon is a bit different from the others), so it might have been better to replace one of them with "Suspension", for example, to make bridge the unique connection.

Solved in less than a minute but I put "supporting structures" and didn't get the point.

thanks
