Cyclones30,
Any chance you're going to CanoeCopia? I hardly know where to start in response to your questions since that area is so rich with all sorts of pluses. We could probably fill a few pages with information for you. It would be easier to chat about it in person. Also, when it comes to sharing info re: fishing (holes), etc., that info IS more freely shared in person OR via PM's.
There are two resources that I believe would be of considerable use for you, if you are not aware of them already. So, rather than hand you fish, I'll share how I go about planning a fishing/canoeing trip:
1) Bob Beymer's book, "A Boundary Waters Fishing Guide" (it covers BOTH the BWCA and Quetico & provides detailed lists of fish species present in each lake).
2) The website PaddlePlanner.com . Membership is cheap and the planning functionality as well as the portage & campsite reviews are pretty darned good.
Here are my short, generic responses to some of your questions:
The fishing can be quite good and there are plenty of 4 & 5 Start Campsites in the area... and PaddlePlanner will show you exactly where they are.
Things to do? Well, you're near the Poet Chain if you enjoy waterfalls. It's fun to walk around Chatterton Falls and to cast a line around the spillways. Also, on that route, you'll have a great shot at spotting wildlife, particularly moose (Deux Rivieres area) and swans (north end of Sturgeon).
Ram & Antoine (& Oliphaunt) can be good day trips and can offer excellent fishing. However, if it has been particularly wet, you may find those short portages over to Antoine to be really nasty mud holes. An issue of the BWJ a few years back featured a pic of a prime vintage mud hole on that very portage, in fact. Might not be where you'd want to take your wife if it has been raining a lot.
I think when you can answer Solotripper's questions, you'll get more helpful responses.
Re:Scripture Island, well, I've only heard "rumors" as to the derivation of its name. As some tell it, back in the dawn of time, an Objibwe warrior who took the tribal name of "Pine Knot", went there to lay down his Commandments regarding the sacred & proper processing of wood for campfires. As I understand, his commandments started out something like this: "THOU SHALT BURN ONLY RED PINE OF FOUR INCH DIAMETERS CUT PRECISELY INTO TWELVE INCHES LENGTHS." I don't remember the dozen or so commandments in the middle but it finished with: "AND ABOVE ALL, THOU SHALT NOT TOSS IN PINE KNOTS UNTIL THE WORD HATH BEEN GIVEN." Yeah, he was a real stickler when it came to sacred stuff like that.
That's what I've heard, anyway, but you know how rumors go. I suppose there's an outside chance that someone on QJ may be able to share a more pedestrian, plausible explanation re: Scripture Island....

Good luck with that one!
Later,
Jimbo
