Cache is not at posted coordinates but is within 1 mile.
Many of us, myself included, pass by this area many times. A quiet neighborhood with tree lined sidewalks, beautiful architecture, and a lovely lake. However about 60 years on this very day of this caches placement, things weren't so quiet for this piece of suburbia. "On July 19, an Air National Guard jet trainer on a routine exercise from Grenier Air Force Base in Manchester, New Hampshire, crashed in the front yard of a home. The pilot was First Lt. Lawrence C. Guild from Quincy, and his navigator, Capt. John F. Murphy Jr. Murphy, a father of five, had lived with his family on Tower Street in Worcester." It was after locating a few caches and waymarks of plane crashes that gave me the idea for this cache. The puzzle is simple; search the web for the information required for each equation to get the coordinates to the final.
Homes at #AAA and #BBB Forest St. suffered extensive damage.
Plane Crash Occurred on July 19, 1CCC.
N 42 17.XXX
AAA+BBB+333=XXX
W 071 48.YYY
CCC+22=YYY
Once you get the final coordinates, add 0.049 to the north and add 0.009 to the south to get the coordinates for parking. The park closes after dark therefore the parking will be too. The cache itself is night friendly and there is 24/7 parking nearby, and I've included it as a waypoint. Shouldn't give too much about the puzzle away.
On January 14, 2018 a very special cacher, RustyRose, came to find this cache; the daughter-in-law of Captain John Murphy Jr. It marks the 4th anniversary of his wife Virginia's passing. RustyRose came equipped with a picture (below) and an actual piece of the plane. I encourage you to read RustyRose and her friend loveair's logs. They are truly the inspiration behind this cache, and its an honor to have descendants and those whose lives Captain John Murphy Jr. touched come to find this cache.
Congrats to scarhill for the FTF!
