Now that you have followed the articles and videos this week of all of the off-road vehicles, I suggest if you have a 4X4 that you use it to the limits it was built to do. Rather than making your massive vehicle the soccer mom or dad car, occasionally drive it out of the city and find an off road route to really have fun and test the capabilities of your SUV. After a rainy season, muddy ditches and shallow rivers will turn into playgrounds to put your vehicle to the test. In California there are many roads just outside of the city that are OHV vehicle approved and would give 4X4 owners great pleasure. A site for off road trails in Southern California is http://4wheeldrive.about.com/od/socaltrails/
So just get out of the house and reward your 4X4 the fun it deserves by taking it off the asphalt and drive it out of the city onto some pleasurable, beautiful trails.
