Here's a blank calendar that I use. I just fill in the dates and draw a line across it from one date to the other to put my morning mileage in.
I have an aluminum clipboard with a flipout section that I keep it in, invoices are in the back section. The clipboard goes everywhere with me.
Oh yeah, I used too work for Ecolab.
Remembering all my departed friends.
Well, I hope everyone is happy now.
