The very first time I was ever on a bike was at a course. Which happened to be Learning Curves. First day there was a rain storm and second day where we did the test, there was a snow storm. Kind of ironic cause the original date I booked for got cancelled due to forecasted snow which turned out to be a nice sunny day.
It is true what the instructors told us that day. After riding in those conditions, we have pretty much ridden in the worst of weather around Toronto. On top of that, we didn't have to worry about dropping the bike too much on those days
(This course took place 1 year ago)
Overall, I think the worse the conditions are during the course (other than hail cause that sucks), the more you get out of it.
You were there for my second apprentice weekend

This weekend is going to suck! I have rider's training at Humber, and the weather forecast looks like it's going to snow and rain.
Curses!
I wish I had reserved for the RTI course downtown a month ago, so I would've taken the course last week.
Best weekend to learn. How perfect that you have your first bad weather experience with teachers there to guide you and our bikes at risk rather than yours.
Plus there is a slight time allowance for weather (it is very minimal but it exists)
