So I've been practicing a bit at the local park. I'm showing up in the mornings, pulling out cans and bottles from some of the trashcans, and setting up small loops. I've been practicing counter steering (or what I think it counter steering) and I'm learning that pushing left really does go left!
I've also been doing longer loops around courses marked by trees and really sprinting from turn to turn. Great practice! Even if I don't get any stronger, improved cornering should keep me safer and shave off seconds - maybe minutes?
