People often express themselves in signs. (See In Praise of the Handmade Sign) Someone in Tulsa has a problem with Jacci and has written about it. It spells out a tragedy and evokes both heaven and hell.
Tulsa is very strict about graffiti in the main part of the city. Whoever has the problem with Jacci adds notes throughout the Eastside. The city cleans up most within a few days, but you can sometimes catch something on private property.
