Church Planting – Reach a Higher Altitude

On a recent trip to Arizona I caught an Interstate 10  glimpse of an airplane graveyard - more commonly known as "The Boneyard" at the Pima Air and Space Museum.   This is a large facility in the southwestern desert where planes are stored until someone figures out what to do with them.   Joe Zentner of DesertUSA reports that the planes are divided into four categories:

• Category 1000 planes are preserved with an eye toward possibly flying again, should international political conditions warrant.
• Category 2000 planes are maintained for spare parts. Some parts from older aircraft, are available nowhere else.
• Category 3000 planes are kept in near ready-to-fly condition, awaiting a more-than-likely new deployment.
• Category 4000 planes are destined for "static display" in museums, town squares or Air Force base entrances. Most, however, will be sold as scrap metal, eventually finding new life as razor blades, soft drink cans or car fenders.

Certain images always take me to church planting - and this was one of them!  After reading the article on boneyard classification I thought about a church boneyard and could there be a classification?

• Category 1000 = for transitioning churches because communities are changing and the churches might change - one day
• Category 2000 = for maintenance churches because they show some signs of life and usefulness while looking for a young pastor who will bring in more young people
• Category 3000 = for churches with a vision to relocate - to go where "our kind of people are"
• Category 4000 = for dying churches because their cemetery grew larger than their parking lot

I'm wondering if America will have a church boneyard soon?  I'm wondering just how long does it take to grow one?
