I've heard from other cyclists that mountain biking trains you in those emergency maneuvers. I was describing them to someone who mountain bikes and he said "Oh yeah, I've done that, yeah, I learned to do that all the time. yup, that one too".
I like to do the quick-turn on just about every corner because it is fun. I like the lean.
I like to try to make the brakes squeal with the instant stop. Especially when there are people to hear.
Rock dodge is fun to practice on actual rocks & potholes, also with leaves and just marks on the road (that aren't an actual obstacle). But I prefer a bunny hop (not advised by the League!)
In fact when we were practicing Rock Dodge during my LCI training, it was getting pretty boring because all of us pretend-students were doing it perfectly and the pretend-instructor was having to say over and over "Good job, very nice". So I did a bunny hop instead--which the real trainer had told us he kicks kids out of his class for bunny hops and wheelies and stoppies. Everyone laughed a lot more than it deserved, because we were so bored with the Rock Dodges! We moved on to something else shortly after I did that! And we made a point of doing things incorrectly so the pretend-instructor had something to say besides "Good job".
