There is no container to find at the posted coordinates. Please read the cache page to figure out how to calculate the final location.
This multicache will take you on a circuit through Davenport, Rock Island, and Arsenal Island. It's designed to be walked or biked. Parking is available throughout downtown Rock Island as well as at Schwiebert Park.
You'll be collecting a series of numbers as you walk, so don't forget to bring a pad of paper and a pen. Any dates you run across should be converted to MM/DD/YYYY. These will correspond to letters A-X which you'll plug into the final formula to find the cache coordinates. Each of the landmarks you encounter should be easy to spot so just enjoy the walk and fresh air.
If any of the steps seem to be missing the info you need, or an instruction is unclear, email me and I’ll check it out ASAP.
Now for the fun!
1. Start at the posted coordinates, N41 30.679 W090 34.515. You will see a concrete plaque set in the brick wall with a musical instrument and a date. The month and day MMDD (ignore the year) is A-D
2. Head east along the bike path on the riverfront and follow it as it curves north onto Arsenal Island. You are looking for a large pillar located at N41 30.984 W090 33.929 with the names of pioneers who contributed to the building of the small wood house you'll see nearby. Find Jane T. Montgomery. The date YYYY that corresponds with her name are E-H.
3. Continue across the bridge into Iowa to N41 31.325 W090 34.172, a no parking sign painted on a wall with a phone number. Add these numbers together. The resulting two-digit number is I-J.
4. Walk along the Davenport riverfront to the Bix memorial located at N41 31.144 W090 34.779. On the last line of the middle plaque there is a Davenport address. The four-digit street number is K-N.
5. Cut northwest to 2nd and Gaines and make your way onto the walkway of the Centennial Bridge. Proceed to N41 30.873 W090 34.873. Do not attempt to complete this step by motorized vehicle! There you will see a number of large crates sitting just to your right about 7 feet off the ground. Find the one labeled “Tollhouse Power” with a red warning label facing you as you look west. Count the total number of letters on the three lines below the WARNING (do not count the word “Warning” itself). This two-digit number is O-P.
6. Continue over the bridge back into Illinois to N41 30.649 W090 34.755. As you exit the walkway you'll find a plaque immediately to your left. Find the date that the bridge became known as the Centennial by the request of Mayor Galbraith. The date MM/DD/YYYY are Q-X.
Now plug in the formula:
N41 (Q+O)(G+D-V).(O+L-H)(R+T-Q)(J+E+U)
W090 (M+W-X-N)(B+A).(I+C-W)(P-X)(F-K-S)
As of August 2014 the cache has moved slightly, but the coordinates should still be right on. The cache is a micro, log only. Bring an extraction tool, and either a ladder or your best shimmying boots. Be safe, stay stealthy, and have fun.
