Skill Level : Advanced
Skills required: Map reading, Geometric construction
Equipment needed: A map of Plattsburgh, NY (more detailed is better). A drafting compass (metal point) , a mechanical pencil (sharp point needed), a protractor (360 degree, or military co-ordinate scale and protactor is best), a straightedge (18" is best)

Contact the Plattsburgh City Chamber of Commerce and ask them for a free map that is good enough to do the job, but you can find better.

You MUST be able to do the following geometric construction!

***Construct a perpendicular line***

TO FIND THIS LETTERBOX

1. Find Route 3 on the map. Route 3 intersects with Broad Street. This is point A.

2. Broad Street intersects with Rugar Street. This is point B

3. Draw a line from the east edge of the map , through point B , through point A, to the west edge of the map. The east end of this line is 90 degrees. The west end is 270 degrees.

4. Construct a perpendicular line EXACTLY between points A and B on line segment AB. Label this new point the ORIGIN. You will use this point to find ALL of my other letterboxes in and around Plattsburgh.

5. Draw a line from the south edge, through the ORIGIN, to the north edge of the map. The north end of this line is 0 degrees, the south end is 180 degrees.

6. Put the metal point of your compass on the ORIGIN and open the arms, touching the pencil tip where Route 3 intersects the y axis. This is your INTERVAL. This will be your reference for distances for all my other letterboxes in and around Plattsburgh. You may want to draw concentric circles, each one expanding by one INTERVAL, out as far as you can. You might want to walk along this INTERVAL (from the ORIGIN to the intersection of Broad and Prospect streets is easiest) and count the number of walking steps you take. For extra accuracy, count the number of steps from the ORIGIN and then back to the ORIGIN. Find the average of the two. It would be good to know how many walking steps you take in 1/10 of an INTERVAL. Divide the average number of steps by 10. This will help you measure distances shorter than 1 INTERVAL.

7. To find the Somnambulist, draw a line 109 degrees relative to the y axis with a protactor.

8. Mark off 3 INTERVALS., Directly south from this point, approximately .3 INTERVALS along a fence, down to the right of a flying manhole cover, in a tree atop a natural stone wall, is the Somnambulist. Can you figure out where he came from?

9. You should be able to walk as the crow flies from the ORIGIN to the letterbox. I highly suggest you do, as it will take you through the college campus. Check out the outdoor art gallery. Take a picture in front of the friendly statue. Check out a game in progress in the fields.

10. ADDITIONAL CLUES.

DO NOT cross the guardrail, it is the farthest east you should go.

Walk Along the chain link fence in the field, do not cross it.

Be careful near the water, keep an eye on children, and take special care during the spring. The water can be very high and fast. If it looks too dangerous, skip it today. There are other boxes in Plattsburgh.

DO NOT PARK ON CAMPUS, the campus patrol will ticket you! You can probably get out of it but but it's better to avoid the hassle.
