Traffic lights - it was time to clear out all the old paint I've been storing. Now I have more space in the garage and less space on my PC!! I also have a 5 gallon bucket full of drying paint mixed with cat litter which supposedly the bin (trash) men will be happy to collect - what a horrible thought as to where it will end up!!!
