To me, Kings Dominion has one world-class coaster (I305), two very good coasters (Volcano and Dominator), one "interesting" coaster (Flight of Fear), and two decent woodies (Rebel Yell and Grizzly). Not a bad line-up at all.
I knew very little about Kolmarden outside of Wildfire, and ended up liking the park a lot. The cable-car safari and animal habitats were very well done--and Wildfire was excellent (particularly that last inversion--whew)! Getting around the place is quite a hike.
^Not this trip, but I did ride it back in 2008. I'm not big on flat rides, but Talocan was the best Top Spin I've ever ridden. It's also the most fun to watch.
^Neither do I. I was hoping to see a slew of Intamin wooden coasters after the success of El Toro and Balder, but it never happened. It worked out for RMC, though.
