You know you've been doing clean-ups when: You can tell which leaves belong to which tree. Even after they've been shredded into dime size chunks. You ask your coworkers to smile so you can see them in the dim light of the dust cloud surrounding you. You lose count of how many times you've emptied your Walker within the past 10 minutes. You are mistaken for Chimney sweepers. After the constant retracing of your mower paths to pick up blowing leaves you begin to sing out loudly, "Let it snow, Let it snow, Let it snow"
