I haven't raised my prices yet, but I have had to schedule what days I do certain counties.  I hated to have to do that, but I can't afford to travel 250 miles round trip every day.  So I divided it down the middle and do 2 counties twice a week, and the other 3 counties 3 times a week.  It was my only solution I had other than raising prices.  We will see how that works.
