I know this is a dumb question but I'm curious how you guys with 100 accounts determine when to stop mowing a particular lawn for the season. I know you could ask them. Is that what you do? - Call all 100, shoot the breeze and then ask if you're done? MY MORE IMPORTANT QUESTION: When you decide you are done how do you leave it with them? (assuming you want them back again next year) Do you write a letter or just a note on their statement? Do you do anything to get an idea as to whether or not they'll want you again come spring?
