I don't know if it's my fav or not, but it certainly was memorable.  It's the one between Mack and Munro Lakes.  It's a pretty good up/down, but that wasn't it.  It was the ticks.  I had the canoe, so I really couldn't stop, but I could see them all over me, and even on the bushes.  At the end of the portage I had to strip buck nekked and wound up picking something like 70 or 80 of them off me.  The zip offs on my pants worked well as tick traps.  The flaps stopped some of them and there were 15 or so trapped there on each leg.  Apparently I'm a tick magnet...
