Welcome to the forum. What wrong with cul de sac riding? Makes you practise turns, short acceleration bursts ... A pic or two would be nice and as Krazy said a short resume of what you learned on the course would be great.
Gotta love the snow/sleet we are getting right now in ME, lol. Luckily here it is mostly sleet and not icing anything over...figures, Monday I was riding! Welcome! Hey, if you want a smaller bike to learn on, I have my 650 Classic in the shed, beautiful shape, I'd be glad to trade to help out a new rider
