While I have no use for these all terrain stairs right now they just strike me as something that may be good to keep track of for future use.

The Hewitt All-Terrain Staircase is the perfect solution for areas where a permanent staircase installation would be too difficult or costly. The system’s unique design allows it to be adjusted to almost any terrain or slope. Customization is easy with several lengths of modular stair, landing and rail units available. No permanent and costly footings are required. Simply use the optional landing pads, or pound the support poles directly into the ground. The lightweight, corrosion resistant aluminum construction makes set-up and take-down a breeze.
