Hmmm! I think Hoaxci5 has some experience with sand!
I enjoy dirt and rock. Just hitting a dirt trail to see the sites is enjoyable. I love rock crawling though. Taking your time to navigate the obstacles is a lot of fun. And makes for good entertainment for those watching!
Mud is fun while I am in it, but as soon as I get home I immediately regret it. The cleanup is so annoying! Plus with how much of these Jeeps rely on electrical components makes them a nightmare!
Sand is fun at first, but the thrill quickly fades. You can only go up and over so many dunes before it just gets old.
