yeah, you would find the castle point loop at minne perhaps a good workout but not much for doing some freeheel turns, but another thing comes to mind.
if you ski the main road at the former Awosting Reserve (now part of minne,) it's a LONG uphill you skin up and then get your jollies on the way down. park car at gate and go from there.
you need good snow cover, so we might need another good storm to make it really doable.
you can reach it via N mountain road in gardiner if you approach from the deli go past shaft road then take the next right past shaft and kind of follow your nose. pm for direction if interested...
