Maybe a side effect of more competition for park riders in the area? A few years ago, Creek was pretty much the only game in town - yes, there was Plattekill, but it's not an easy day-trip drive and while Launch tried hard, but the simple fact is Spring Mtn doesn't have a lot of elevation to work with. Now Blue and Thunder competing for riders. Blue really needs a proper top-to-bottom jump/flow trail to get taken seriously, but Thunder has definitely invested some serious $$$$$ into making it a place that can really compete with Mtn Creek and even Highland.
