Pterodactyl Tri Bike Course?

We ride this course almost every week and everyone seems to like it.  Some people think its hilly, but compared to Kensington its pretty flat.  It does have a few decent hills but nothing terrible.  A guy I rode with last week said he thought it was close to ride at Steelhead.  There's only one kind of scary turn that goes under the rail road tracks as you're going downhill.  There's also not much traffic on the roads - its not a through road like Kensington so the only people you get driving it are people who are going to the park, not people just passing through.  The condition of the roads is great - very smooth - there are only a few chewed up areas, but nothing to really speak of.
