2008-01-06. Now you can find the answer to question no. 3 (which has caused som confusion) right here on the page if you look carefully :-)
2005-07-22. Hopefully the last adjustments after the move...
2005-04-20. There has been some changes, both in the formulas and the final position.
You have to find the answers to all of the clues and use them in the formulas below. You don't have to visit the listed bridges, only the last one. If you don't want to travel, you will need a map or a mapping program. The answers can preferably be found on the Internet but could probably be found at a library or somewhere else.
The clues will be a bit difficult to find if you don't understand Swedish.
The cache, a 0,5 litre Curver-like box.

where the letters correspond to:
AA=ANSWER1/ANSWER3/5-16
BBB=ANSWER2/3+185
CC=ANSWER5xANSWER7-12
DDD=(ANSWER6-ANSWER4)*2+26
Use the integer part (Sw: "heltal") when you have to round the figures.
Please always confirm the final position by mail before you go there since some of the questions are possible to find more than one answer to! Or use Geochecker (Link below)
TIP! There is a good parking area 200 meters from the cache, in about 330 degrees.
