Geo-Tracking my Snowboard runs through Snowbowl

I'm really starting to like geolocation and it's many uses. Recently I've been checking out the different things that my iPhone can do with it's GPS. Yesterday, I let iTrailMap 3D run while I boarded around Montana Snowbowl. It's really interesting to see where we went through the trees and where we still had to yet to hit. At one point I even took it out to see where I went last time, so I could pick the next line better. It's great cause it has a "you are here marker". Two improvements I could see would be better map resolution and being able to have a you are here dot on the trail map section. A little expensive at $5, but still really cool.
