Why do you have a spreadsheet for your Harley?
I keep track of gas and expenses.
It's interesting seeing the price over time. I've recorded every drop of gas I've put in it since I bought it. 21k miles and 540 gallons worth. :-)
It's funny, because I started working from home a few months ago, and you can see the usage plummet to almost nothing. I was filling up every 6 days or so, and it went to once a month.
