Just got around to getting the trip report on Smith Creek up on my blog. Visited the upper area and the special reg area in late September based on the recommendations in Flyfisher's Guide to Virginia.
While it was a pretty area as you can see from the picture, the fishing was terrible. This is stocked, but was stocked way back in April - pretty much nobody home at this point in the year. Caught a number of small chubbs on a Mr. Rapidan.
There is good walk to get here down a steep hill. I advise against this spot unless you know it has been refreshed.
