Great!!! When I lived in Maine the streamsides were full of the 'tents', never actually thought of coming up with a fly pattern though. Then I was sitting around the other day trying to think up some new patterns to try when I take the kids up next year, and inchworms & tent worms were the the only things I could think of.
We used to take the live worms and use them for bass bait, which always worked, I can only imagine that trout would love them too. I'll have to play around this weekend and see what I can come up with on the vise.
