Sooo.... out came the roll of masking tape, and here's how Sweetpea and ArrowBoy spent the morning!
If you look closely at the photo above you can see the road going up and over the armrest of the couch!! It then turned right across the seat to connect again to one of the main roads on the carpet.
See the airport above in the bottom right hand corner? And opposite that is the site from where various (tiny) construction vehicles are dispatched to new building sites all over Carpet Town! And in case anyone is really studying the details of these pictures: Arrow is wearing a rather garishly shining nurse's outfit over his clothes - he found it in his sister's dress up box and when we were reading Nurse Nancy prior to 'building' our roads, he wanted to play the part! (Really need to order Doctor Dan for him a.s.a.p!!)
