Pete and Franco at Pesda Press have come up with a layout for the Scottish Sea Kayak Trail book which is a little different to their existing guides. Closer to a Rough Guide I'd say.
Two columns with full page box-out for the asides on history and out story. There's a neat reference marker down the margin so you can see where you are on the pages.
They also want to create yet another box out. I've been asked to pull all the facilities information (shops, busses etc) out of the body of the description and put it in its own area.
Of course it's the correct approach. I kick myself for not thinking of it earlier.
