I didn't mention it, but we only encountered one boat on the whole trip.  They graciously slowed down as we passed, since there isn't exactly a lot of room to avoid big wakes.  I was actually surprised, because there were several trailers at the landing where we put in.  I guess they all went the other way.
  I don't exactly like the fact that the water clarity is 4 mm.  I like to see what I am about to hit.  However, it was still fun and we didn't hit anything significant anyway.
  From your experience, are there good entry points around any dams in the GF area?  The one dam we had to portage wouldn't have been bad if I had paddled up a little farther and noticed the ND landings before getting out, but I didn't want to risk getting sucked in by too much current with two kids in the canoe.  I did learn enough to look for a better exit point at the end.  I found a landing with enough gravel thrown in to keep me from sinking while I helped the kids and the dog out.  Then I just portaged over the bicycle bridge to the parking lot where my wife was to pick us up.  
  All in all, it worked out to be nice cross training for my Q trip in mid-June!
