In the spirit of athletics the rock climbing arch and skating ribbon represents, I'll let you find the distance and angle to travel.
Distance In mm: the product of the number of vertices of a dodecacontachoron and the highest score of a single dart throw plus the product of the year of the US Olympic Boycott and the number of events in a decathlon. (Use correct mathematical order of operation for the calculation.)
Direction in degrees: determined from the big number on the building across the street, minus the number of degrees in a straight angle.
Notes: 1) Parking is not free. 2) Please adhere to park hours and rules. 3) You can NOT actually get to the arch during all parts of the year. You DO NOT need to! Please DO NOT cross the ice ribbon and DO NOT cross any gates, fences or chained off areas!! DO NOT DO IT unless you want security to give you a citation for trespassing! You have been warned now more than once! 4) The GC5JHPJ geocache listed location is a "virtual" starting location on the pathway. This is just to get you started and is not at all used in finding the cache. 5) The geocach waypoint to calculate from is the actual point under the arch listed under waypoint AA5JHPJ. 6) The difficulty represents the difficulty. Yes it is here and the math is correct. DO NOT move anything in the park! This will not help you! The cache is NOT in or around a garbage or recycling can. You DO NOT need to open anything or move anything to see the container! Please DO NOT move or turn over anything in the park! No more hints. 7) BYOP
