Well you're too generous with your encouragement, but thanks! I'd forgotten that I did troll a brand new black and green wedding ring for a short time as well as the pink one, without a strike.
The fly rod is new to me - just got it last year. So I'm still getting the hang of that. I trolled with it once last summer in a couple high cascade lakes off a friend's pontoon boat, but I couldnt figure out how to do that in my (bigger) boat. All the other fly fishing I've done has been on moving water so I wasn't sure I'd have any luck just casting the Woolly Bugger and stripping it in. Ah well, next time.
The techniques you all list here, including the ones you mentioned in your post above, are all helpful, so keep posting them! I want to get some serious fishing in this year both on flies and on hardware with my kids. My 13-year-old daughter has already been informed that she needs to man the rods next time while I row! She's amped.
