At the posted coordinates, you will find the facade of the "Heigold House". Here's some background information:
"Christian Heigold, a German immigrant and stonecutter, came to Louisville sometime prior to 1850, and in 1857 he built his home at 264 Marion Street in an area known as the Point."
"This was a period of unrest and attacks on Irish and German immigrants, not long after the infamous Bloody Monday incident in 1855. In order to prove his patriotism and loyalty to America, he [Christian Heigold] carved inscriptions and busts of American notables into the facade of the house"
Read the information plaque and inspect the facade to solve for the final location. You are looking for a camo'd preform tube. The final location is nowhere near the railroad tracks. When searching for the final, there is no need to leave the sidewalk.
The cache is at: N 38° 15.ABC W 085° 43.DEF
Where:
A: At the doorway, there are four digits carved in stone ... 18 and 5A.
B: Near the top of the facade there is a bust of President James Buchanan with the caption "Hail to Buchanan, Now and Forever". If The President is looking directly up Frankfort Avenue, then B=3. If looking east of Frankfort Avenue, B=2. If looking west of Frankfort Avenue, B=1.
C: From the information plaque, how many vertical steps must you take to get to the concrete slab directly in front of the Door to Nowhere? Let C equal that value.
D = The number of 12 pane windows in the facade.
E: On the front of the balcony is carved a scene with George Washington. E equals the total number of people carved in this scene (you may need to take a photo with your phone and zoom in).
F: Christian Heigold died in 18F5.
