Looks like you're sticking to the "major" roads in the area. Still amazingly fun, but some of the roads not on that map are much better. Never know how much gravel is on them though, so good call sticking to the more traveled roads.
If you want, I can easily give you some road names in between the mall and where you're heading (namely skip 15 through Sparta and take the back roads through Andover). Unless you think you've got enough twisties already.
