My fovorite beginer motorcycle and car road is the short road to lock and dam 2 in Hastings http://www.bing.com/maps/?PS - Bing has it wrong, it is the squigly line to the left of where they placed it.
If you decide to come out here I will happily put together a route sheet of quieter, twisty roads to practice on. An easy to understand loop would be perfect.
I would be a little iffy getting out this early in the season with him just because i'm sure theres loads and loads of gravel on those twisties
