Well 'round these parts it is.
I remember when the Da'vinchi code came out and all the churches for miles around had the same "Davinchi code explained" series going.
If you go into the Family Christian stores you can buy the series' for any topic you can think of, full sets of things, like sermons, color leaflets, handbills, notes for parishioners, etc..
Or you can buy huge kits for vacation bible school..
Last year, the kdis began to notice that "This years'" vacation bible school themes were very similar...
You either chose the "Make a ssplash", Rodeo or Baseball themed vacation bible school... as we drive along the roads and freeways of Houston... they all have the same banners, different denominations, no relation of churches.. they just happened to have bought THAt particular vacation bible school set..
Now, this is not that I am saying anything is wrong with it..
I was just simply trying to explain what the billboards were for.
