...are Grayman's workshop!
One of his latest creations is an ultra large mat named "Shirley." The red one on the left is around the size of a 4GF Standard. (My lawyers are looking into that!) So that makes the mat on the right massive. And with no non-skid on the deck, it might be a little slippery! :)
The other project is a plywood Paipo. Following the lead of Surf Sister, and apparently a number of other prone riders of late, Paipo mania has struck!
In truth, I'm intrigued by the concept of a plywood prone rider. They seem to be a really interesting counterpoint to mats. This summer may see a few coming out of the 4GF skunkworks.
