Jim,
Ignore the comments by all of the bozos
You can't address the issue until you factor in all or most of the issues.
For example, are your fairways wide, narrow or medium ?
If they're wide, a case can be made for difficult rough.
GCGC and Mountain Ridge have wide fairways and difficult rough.
Secondly, it's rained a good deal lately and the rough everywhere in the area is thick and difficult, hence you have to consider it's difficulty under normal, not very wet conditions.
You can reward accuracy off the tee in a number of ways, and one of them is to have difficult rough.
Is your course on the short or long side ?
Aronomink for example would be a long difficult course without challenging rough as a defense.
Other shorter courses might require difficult rough as an integral part of their defenses,
But, you shouldn't alter play/the course in order to accomodate the lowest common denominator amongst your golfers.
Once you've assembled all of the influencing factors, you can make a prudent argument.
Without the facts, you'll just sound like TEPaul
