A lot of pros live in Whistler/Pemberton/Squamish... it's really not THAT big of a deal to see one around. They even work, go to the gym, take children to swim lessons, and ski on the same mountain as the public! *Gasp*
OHMYGOD THEY MIGHT EVEN WIPE THEIR OWN ASSES TOO!
But seriously, if someone started a thread for everytime they saw Sarah, Mike Douglas, Rex, Hugo and everyone else, we'd have 50+ posts a day just on sightings. They're normal people... who just happen to be damn good skiers.
