Winding your way through County S, you'll find lots to see and lots to explore.  This is a pro track (not necessarily pro driver) because of two extraordinarily long jumps.  A lot of work has gone into the making of this track, but on the whole it gets bogged down by far far too many high vertex objects placed randomly and haphazardly around the track and by an excessively long train that serves no other purpose than to thwart rookie drivers.  If your system can hack the lag, this one is worth a go.
