A number of decreasing radius off-ramps around Fredericton. I love bending the bike down into those when traffic is clear.
Going from Riverview (Moncton) to Hillsborough, there is one particularly treacherous corner. It's got it all: right-hand, blind, sharply downhill, decreasing radius, off-camber, rock face on the inside and deep ditch on the outside. I almost lost my Escort GT there one spring, lots of opposite lock and just made it around with the back wheels in the gravel on the wrong side of the road. Fortunately it was very early in the morning and no on-coming traffic. Lesson learned: Signage in rural NB should be paid attention to.
