This is a quick multicache to help your numbers.
NOTE: THIS CAN BE A VERY HIGH MUGGLE AREA. PLEASE US DISCRECTION CACHING HERE, AND TRY TO VISIT WHEN THE MUGGLE NUMBERS ARE DOWN.
Go to the posted coordinates. You should see a 2 part sign that I thought was kind of odd. I decided that this might be a good place to start a 2 part multicache.
Underneath the sign there is a prominently displayed black number on a white background. Add together the last 2 digits of that number, then add that to the last 3 digits of the North portion of the coordinates given above.
Look at the sign itself. On the bottom line there are 4 words. Count the total number of letters in the first 3 of the 4 words. Subtract that number from the final 3 digits in the West portion of the coordinates given above.
Now you should be ready to go hunting for the final. The final is within 2 miles of stage 1. Good luck, and have fun. And don't forget to avoid the muggles at both stages.
