This is a cache that I have thought about putting out for some time. I intend for this to be a straightforward puzzle that a little online research should be all you need to determine the final location. Final location is not quite wheelchair accessible, but mostly because of tightness.
The final coordinates are N 39° 3A.BCD W 76° 5W.XYZ
Don't look for the cache at the listed coordinates, but you may drive thru them depending on where you're coming from.
Use the following questions to determine the actual final location of the geocache.
A = YEAR MARYLAND WAS ADMITTED TO THE UNION (4th digit minus 3rd digit)
B = FAMILY NAME ASSOCIATED WITH THE BLACK AND GOLD QUARTERS OF THE STATE FLAG (number of letters)
C = YEAR LORD BALTIMORE WAS GRANTED A COLONIAL CHARTER FOR MARYLAND (3rd digit times 4th digit)
D = THE YEAR THE SURVEY OF THE MASON-DIXON LINE WAS COMPLETED (4th digit)
-------------
W = DATE THAT FRANCIS SCOTT KEY WROTE THE LYRICS OF THE STAR-SPANGLED BANNER (2nd digit of the date plus the 4th digit of the year)
X = YEAR CHESAPEAKE BAY BRIDGE OPENED (3rd digit)
Y = NUMBER OF STATES MARYLAND BORDERS
Z = ANNAPOLIS SERVED AS THE US CAPITAL UNDER THE CONGRESS OF THE CONFEDERATION FROM ____ TO ____ (subtract the starting year from ending year)
CONGRATULATIONS TO Trevelyan's R&R ON BEING FTF AFTER JUST 55 MINUTES!
