That you don't have a NARGS chapter but do have other active clubs would be a good part of the GUIDE. I really see it as the starting point for a rock-gardener (well me really) who was planning a visit and wanted to know just those things you would want to know - what gardens are worth seeing - public, private (are the locals friendly); where can I see great wildflowers; when should I visit; what meetings or outings does the local club/chapter/group have; where can I buy plants etc etc. What's the nicest, cheapest, most fun place to stay etc etc.
Of course whoever writes one of these will change this to match what they would want to tell someone about where they are but you get the idea. It should be fun to write - then it'll be fun to read - maybe you could get sponsored by the local tourist board!
