"Formerly Bekin Road, a “made” name from abbreviating the Balingup/East Kirup/Noggerup Road, it is now just Grimwade Road.
It was not until the early 1970s that the Department created its own Nomenclature Committee.
From then on, while name generation continued to be from the field, the final decisions on acceptance lay with the Committee whose decisions, and in most cases with an explanation for the choice, were formally recorded. "

I live about 20km from this road. I have driven it many times. I have seen the signs with my own eyes. The signs say Grimwade Road. Go and have a look for yourself. The signs have been erected by Main Roads.

The signage on the ground says it's Grimwade Road. Why on earth would you call it anything different to what the actual signs say?

Using Google street view, the actual sign for the road at the Noggerup end says Grimwade Road. Have a look for yourself. The sign is about 100 metres up from the actual intersection.

I think you are being far too pedantic. The bush and trail surfaces vary greatly over the length of the Mundabiddi and trying to make them "consistent" will means that some are right and some will be wrong. The nature of the trail and site is not consistent so each should be labelled according to how they actually are. Don't change them until you have seen them. I have made the effort to visit all the trails I have marked and there is nothing more annoying than an armchair mapper ruining my work.

Yes, they are sites for tents. Not huts. Have you been there to inspect them personally?

Why are you changing anything? Do you live in the area? Leave it alone, don't interfere with peoples work.
