There is a fundamentalist group of wanna-be Christians here in Ocala who believe, mistakenly, that planting "prayer" signs in the grass around town is what Jesus meant by "evangelism." I've tried to help them out by giving this photo a watercolor look but I'm afraid it will make little difference.
One clue that maybe they've got things wrong is that the signs keep disappearing and must be constantly replaced. Another clue is to be found in the directional sign atop the post in the middle of the picture. The way they should go is confusing. But they refuse to give up. This particular sign, for example, went missing for several months, and now, "Presto!" it has returned!
