I have another multi called 'The Road Goes On Forever' which is a 4 stage multi. This one is less work, and is only a 2 stage multi. At the posted location, you will be looking for a label on the back of a sign, which will give you coordinates for the final. There should be room to pull off the road nearby.
When you get to the final location, look carefully, and be sure to replace as you found it.
