I have visited Renton Municipal Airport on plenty of occasions but I had not previously stopped to check out the sculpture at the entrance to the airport.  It is sited by the main gate and there is a parking area to make it easy to visit.  The formal name of the airport is Clayton Scott Field and the sculpture is of Clayton Scott himself next to a sign showing the direction and distance to multiple locations.  The top of the sculpture even includes space as one destination!  The locations are chosen and organized to provide a nice spiral pattern to the markers.  It is a nicely executed piece of artwork.
