Hello Talk

I see where you are comming from Karl, and it's a good solution.

However, I do feel that a landuse tag would be better, as in my case here in 
Cyprus we have fire breaks that are NOT in a wood or forrest. We have a very
combustable grass about half a meter in height along the mountains that has 
fire breaks.

Also, as a previous post has mentioned, fire breaks are good navigation 
aids, and just having them as a track would not make them stand out. As in 
my case here the vast majority of fire breaks run along a track anyway.

Am busy making ravel arrangements to return to the UK, but next week I will 
make a proposal unless someone has a major objection.
