I am sad to say I didn't even know Quetico existed until my 34th year.  I re-tell the story of how I discovered Quetico in the QJ Stories section (see:   (You need to Login or Register , especially beginning p. 2).  Before that it was the Allagash Waterway in Maine and many different rivers in Virginia & the Carolinas. Since discovering Quetico in 1988 I've done close to 30 trips there; a couple of those were done via the BWCA... a park which I really do not know well. 

A few years back, Kingfisher, dentondoc, Magicpaddler, Quentin, a few others, and I tackled Woodland Caribou Park for the first time (see:   (You need to Login or Register ).  KF & I went back to WCPP to attempt something a bit more audacious the following year (see:   (You need to Login or Register ).  I guess we were seeking some variety and, perhaps even more solitude.  DD's comment re: saplings & even full-sized trees growing right through the center of fire rings is right on the money.  Up there you have a danged good chance of putting your boots where very few have ever tread before.  My thanks to Marten for his stories re: that special place.  His stories & prouboy's got me started there and I do hope to return.

I get a kick out of "new" water & almost always try to work some in during a trip. 

It'll be a couple Q trips for me this year but I am seriously considering an Opasquia trip for 2014, mostly in search of new stuff, I guess.  It should take solitude to a whole new level.  I think the visitor ratio of these parks is something like this: Quetico: WCPP: Opasquia = 600,000: 600: 6.

Maybe someday I'll make like Jim J. Solo & head for Arctic watersheds (at least before my back finally gives out for good; alas, I fear that time rapidly approaches!).  My interests seems to be drifting in that direction.

I don't really favor one park over another.  Any of these parks can be a wonderful place for me with the right companions.
