Sometimes it gets late when you're making snow. Often, you're working in inclement weather, and may not have the window for making white gold that you'd like - you may be stressed out. That's why it's very important to prepare for this eventuality as best you can. Let's say it's 2 or 3am, and you're in the excavator:  will you remember what you're supposed to do, even if you've already run 200-300 other loads of snow out to the loop? Hard saying. That's where this handy reminder comes in:     OOOOooooo. Yeah. That's where it goes. Catastrophe averted. Now go pave the rest of the loop with snow!
