I spotted a sign at the published coordinates and it got me thinking "just what would fit the limit?"
You don't need to answer that question, but if you answer the questions below you will be rewarded with a cache.
The cache is at
S41 23.ABA E172 49.CDB where
A is the number of letters in the word that starts with V.
B is the number of bicycles on the sign.
C is the number of 5 letter words on the sign.
D is the number of bikes plus the number of people plus the number of wheels that you can see all or part of.
The sum of the six missing digits is 32.
