The Land Cruiser
In order to get around on the property (and, yes just to have fun), we bought a 1988 Toyota Land Cruiser, which has been an absolute delight. I have yet to meet anyone who does not enjoy the idea, if not the reality, of 4-wheel driving across open land.  Of course, there has been a learning curve, as we have taken it across creeks, springs, snow and mud.

One of our projects for this year is to put gravel on over a mile of driveway, but until then it does cause some driving challenges!

  Our driveway gets a "little" muddy

Although I have been able to dig myself out a couple of times while crossing creeks and driving on the hills, last June I drove into a live spring and the chassis hit bottom immediately. I spent a couple hours trying to dig myself out with a baby shovel, but in the end I walked for several hours to find a thoughtful neighbor who pulled me out.
