Very very good conditions at the moment!
RE the lockers. If you don't leave anything of value in the bag you can just leave it in the daylodge. At sunshine if I have a bag I just leave it in the snow outside the day lodge. Heaps of people do it. Just don't leave gold or Jewels in it!
I'm from Toronto, I'd be anal about someone stealing my bag the entire time haha! Plus its not even my bag, owner of my local snowboard shop let me borrow his so rather not take the chance of some kid taking it.
As for the snow i've been creeping LL and Sunshine webcams and it looks bomb as fuck!
