Thank you for your excellent post.
Last saturday I got out a map and began looking for access to water, then went out to see what a few areas were like (without my rod and reel). Sunday I went back to one, the area just below the dam at Blackstone Gorge, with rod and reel in hand. Started with drys and didn't catch anything and, after about 30 minutes, switched to wet flys and caught the first on the third cast. Although they weren't "glowing", the area did have an odd smell to it.
I guess it will just take some time in exploration to find these nearby spots. If anyone else can offer any suggestions, I'm certainly open to them. Thanks again!
