We paint a centerline on our grass runway but as you can imagine it has to be renewed every couple of months. We are looking for suggestions (serious) on how to make a more permanent centerline....short of paving and painting.

On 6/2/2004 8:19 AM Ted shuffled out of his cave and grunted these great (and sometimes not so great) words of knowledge:
This is labor intensive, but will work.
Take some 2x12 PRESSURE TREATED lumber, paint it a contrasting color (Yellow, maybe white). Lay out a C/L on the runway with string. Dig down and remove the sod and loosen the soil underneath it. Bring in some pea stone for a sub surface and tamp down to make a firm base. You want the wood to be flush or just a little above the surface of the ground. This will last for years and allow mowing, it is also wide enough to be visibly seen.
You could probably do the same thing in a PVC, although I don't know how well the fastening stakes/pins will hold it for long periods of time. The weight of the wood will hold it down pretty well.
Hope this is of some help.
We use creosote, a petroleum based product for waterproofing wooden sheds and fences, applied with a garden spray close to the ground. It kills the grass and stains the soil dark brown, producing a stripe about 4 inches wide. It survives rain and mowing for about 6 months before it just about disappears and needs redoing.

Roundup!
Over time, the use of lime will harden the ground and become pretty permanent. Do it like the field liners do it! You can get a hand liner or a wheel type and do a pretty decent job of it.
Good luck!

Paving stones or similar.
Yeah, but then you will have to deal with wind erosion. We did that and it took 15 years for it to go away.
Nah, it just went right down the centerline most of the time. Something about being aligned with the prevailing winds I think.
