Nope but pretty close. Actually, I did get a box full of vintage bicycle stuff one day, and, had that box been full of snow, the snow would have, indeed, been yellow.

The box was filled with Suntour vintage road bicycle display stands, all brand new and covered in mouse urine. With plastic gloves and a face mask on, I cleaned and bleached the stands and have them to this day. I use them often when running a Bicycles for Humanity Yard Sale. And, just to make some of you drool - the bike with the stand, a fully rebuilt/converted Single Speed, sold for $100.00. Everything else pictured sold for either fifty or sixty dollars and all the bikes were in perfect working order, some had been completely rebuilt...
