Picture in picture - no, not the feature that your TV had to have back in the 90s. I just found this ad from the resort Northstar at Tahoe in the current issue of Transworld Snowboard Magazine. Sorry for the quality, I just took a snapshot with my cell phone from it.
Can you see the graphics of the obstacle? I shot the photo for the graphics with Eero Ettala last year in Munich (Client: Oakley). It's him standing "inside" the rail armed with a marker and writing stuff on the plexiglas. Kinda funny to see the rail appear in photos every once and while.
