Welcome Maicoman18,
Jerry's Plains is not exactly half way between Singleton and Muswellbrook it is more like 35-40Km to the west of both. I suppose it is half way if you travel from Singleton to Muswellbrook via Jerries Plains (not sure why you would do that)!
It will shortly be overlooking a massive open cut mine. Having said that it is currently a great little country village on the Golden Highway (Hwy from Newcastle to Dubbo). The area has some of the most fantastic riding country around. There is a strong dirt bike community in the area. Singleton, Muswellbrook and Denman all have active clubs and Heaven VMX is very active in the erea. Denman has one of the most active Twin Shock Trials clubs, relavants to you, not sure!!
Anyway welcome to our area. Due to the mining and power generation industries the area, I believe, has the highest average income in NSW outside of the Sydney CDB area. Not sure what the relavants of that is either but I hope you get your share. Cheers!!!!
