Audru is the manor near Pärnu with most buildings. Winding river, the bridges (also suspension bridge) over the water and wide park, which includes three eyots (holms) - all of this creats moody sights. There's also a bandstand on the island.
To seek for the cache, find a parking spot and the way to the park. There are several bridges waiting for you. You are interested in three of them, which are seen on pictures. You will have to do some counting and conversions: XXX = 8xC + B/2 and YY = A and ZZ = B/2-1.
Cache coordinates: N 58° 24' YY.ZZ" (format DD MM SS.SS) and E 24° 21.XXX' (format DD MM.MMM). Both coordinate formats are used to give users with different taste or habit an equal chance to recalculate.
A - Find two similar bridges. In the middle of the bridges there are arbours (buttressings) between the bridge and wire rope. Count them on both bridges.
B - Number of wooden boards in bridge's cross-section.
C - There are wire ropes holding up the bridge from both sides. Count all the vertical hooks the bridge is hanging on.
The cache can be found without all this trouble ;-)
