Huh, that rock looks familiar…
The Hiker really enjoys the great outdoors. While everybody else is watching TV or playing video games, he’s rolling up his sleeping mat, grabbing his compass and map, strapping on his backpack and boots, and heading out to a rarely-trodden wilderness trail so he can spend his time taking in the fresh air and walking around in nature.
Nothing brings down the Hiker when he’s on a hike. It may rain and thunder, or he could be covered in itchy bug bites, or he might even get completely lost and turned around, but you know he’ll have a great time anyway. There’s just one thing that he likes better than hiking outdoors all on his own, and that’s having some pals along for the journey!
