Yeah, depending on how the 15 miles was spread, that would be a long ride in a Ranger.  I figured up I run about 6 miles every morning just choring.  When I start calving soon, I will be making that 6 miles probably 4-5 times a day, and likely even more.  I had a hard time choking down the purchase price for the Ranger, but in our operation we use it a whole bunch.  Sort of like buying a good backhoe for the farm.  Its hard to choke the price down, but just having it makes is worth while.
