Instructions:
1. Assume VCC/GND connected. Use the switches. Read display.
2. If you end up in Brazil, switch N and W ;)
3. Check your answer. If result=true goto 4, else goto 1.
4. Make a note of the hint from the geochecker and remember to practice stealth when getting the cache this is a popular walking area for two- and four-legged muggles.
Please take care to replace cache exactly as found and make sure it's not easily seen from outside. Cache has been muggled once and I hope it doesn't happen again...
