oh ya, I love climbing that hill, what a rush. When I first started climbing it, i had to use gears 1 and 1. Over time I've managed to get into the second chain ring. I love seeing improvement in myself, what a motivator. Its about 30km from my house so I would usually ride 20km past Rattle Snake Point, then turn around and come back to make it a 100km day.
If you continue down Appleby and turn right onto Campbellville RD, your first left will be Nassagaweya 6th line. This is another awesome hill and maybe more challenging. This one is a straight road with a very steep grade and seems to go on forever (steady climb until 15 side road). Coming down my bro hit 75 km/hour. There is a rock quarry on that road, so watch out for the dump trucks.
