I guess another tip for maximizing time on the snow has to do with gear:
1) Pick the goggles for the worst possible conditions you'll experience during the day. I've got some goggles that are great for bluebird days, but horrible in flat light. So most of the time I select my orange goggles when leaving the truck.
2) Make sure all other accessories you need for the day are with you. My face mask is ALWAYS in my jacket pocket, in case it gets windy/chilly up top. If the weather is unusually cold I'll wear the cold weather jacket, otherwise it's the spring jacket all the time.
3) Tie your boots properly the first time. I'd say it's a bit of an art to get the right tightness in the parking lot, but the closer you get the less often you need to adjust. My fiancee is constantly adjusting her boots and it slows us down. Boots with easier adjustment would help here too.
4) If you have a quiver, pick one board to ride for the day, or pick two but bring them both to the bottom, and lock one up beside the lift. I'm not returning to my truck during the day, so if I want to swap to a park board it better be beside the lift waiting for me!
